Karlsruhe Audio Tour: Gardens, Justice, and Contemporary Wonders

On your right, you will see a large, multi-tiered bronze fountain featuring a central statue of a robed woman standing above a wide circular basin, with smaller figures of children sitting around its rim.

Let's talk about Wilhelm Klose. He was a wealthy painter who inherited a considerable family fortune, and he knew exactly how to use his money to exert power. In 1905, he decided to gift this fountain to the city. But there was a catch. Klose dictated everything. He demanded the sculptor be Johannes Hirt, controlled the entire design, and forced the city to place it right here, squarely in front of what was then the main entrance to the grand bathhouse behind it. You could say it was generosity wrapped in a very rigid ego.

The central figure is Hygieia, the Greek goddess of health. The word hygiene actually comes from her name, making her perfectly fitting for a bathhouse. If you look at the app, you can see how her image was already featured up in the triangular gable, the classic peaked roof section, of the building directly behind the fountain.

But getting this project approved required navigating intense local paranoia. A year earlier, another fountain in the city caused a massive moral scandal because it featured an unclothed female figure. The city council was terrified of another uproar. To force his vision through and prove the unclothed children on his fountain were purely symbolic and not an offense to public decency, Klose had a fully functioning, ninety centimeter tall scale model made from pure copper. It was an expensive, physical piece of evidence created just to calm the skeptics down.

Fast forward to 2013, and the fountain faced a much more literal problem. One of the bronze girls sitting on the rim was stolen. Thieves violently sawed off the forty kilogram figure, likely intending to sell her for scrap metal. But they realized it wasn't easy to fence recognizable stolen art, so they dumped her in a forest near the town of Bellheim.

Locals found her, had no idea where she came from, and simply set her up on a rock by their main road. They affectionately named her the Spiegelbach mermaid. It wasn't until a sharp-eyed citizen noticed the official logo of the Karlsruhe baths, which features this very fountain, that the mystery was solved. The missing figure was restored, the brutal saw marks were repaired, and she was brought back home in 2014.

Despite Klose's absolute insistence on placing his fountain at the center of attention, time ultimately had other plans. If you check your app, you can see how the old entrance used to frame it. Over the years, the plaza was redesigned, and the main bathhouse doors were moved. Klose's unavoidable welcome monument was quietly sidelined, left somewhat stranded at the edge of the square. Still, the fountain is freely accessible around the clock, twenty-four hours a day. Now, let's take a closer look at the bathhouse directly behind the fountain, revealing another hijacked donation, as we head over to the Vierordtbad, which is just a one minute walk away.

On your right is the Vierordtbad, a long, two-story structure of deep orange-red brick accented with arched windows and anchored by a striking, minaret-style chimney towering at the far end. It is a beautiful piece of architecture, but it was never supposed to be a bathhouse.

Heinrich Vierordt, a wealthy banker, left 60,000 Gulden to the city, a massive fortune at the time. He did not want a public bath. His grand ambition was to fund a massive, covered market hall. But the pragmatic, stubborn market women of Karlsruhe absolutely refused to move inside. They had sold their goods on the open streets for generations, and they saw a confined, indoor hall as a terrible business move, launching a fierce protest to kill the project.

If you were the city council sitting on a pile of donated cash for a project the locals actively hated, would you force it through or creatively repurpose the funds?

The city chose the latter. They took the banker's market hall money and built this public bathhouse instead. Opened in 1873, it was designed in the Neorenaissance style, an architectural movement that revived the symmetry and grandeur of classical European antiquity. Check your screen for a photo from its opening year to see exactly what that grand vision looked like back then.

The collision of an aristocratic banker's ambition with the stubborn reality of working-class market women resulted in something the city desperately needed. Around the turn of the century, most people did not have bathrooms at home. Saturdays became traditional wash days here, where entire families would often use the exact same tub water, one after another, just to be clean for Sunday.

It also has a history of quiet rebellion. In 1945, French troops requisitioned the bathhouse exclusively for allied forces. But a brave employee named Herbert Hasenfus secretly snuck members of the local water rescue association in once a week. They needed the water to keep up their life-saving training, and eventually, they convinced the military to officially legalize their presence.

The facility continued to modernize, eventually phasing out the old tub baths by 1981, largely because home plumbing had finally made them obsolete. Interestingly, the deputy director of the baths at the time actually used one of those retired bath cubicles as his daily office. Today, it remains a fully functioning health and wellness center, open most days from ten in the morning until eleven at night.

Let us keep moving toward the administrative center. Our next stop, the Badenwerk AG building, is about a six-minute walk away.

On your right is the towering, rectangular skyscraper featuring a striking grid-like facade of glass and aluminum panels topped by several prominent rooftop antennas. Or at least, that is what stood here for over half a century.

When the Badenwerk administrative building was constructed between 1961 and 1965, it was meant to be a bold exclamation point on the city skyline. The architects wanted to bring a slice of New York to Karlsruhe, modeling this twenty-story, seventy-meter tower after the United Nations headquarters. It was a prime example of the International Style... an architectural movement that favored stark, unornamented geometric forms and modern industrial materials. To build it, they used a daring method, pulling a central concrete elevator shaft into the sky piece by piece before wrapping it in a delicate, hanging glass curtain.

For decades, it was a gleaming symbol of modernization. And with grand corporate headquarters came grand corporate art. Out front stood a delicate sculpture of a flute player, while an eighteen-meter steel monument pierced the sky nearby. It is a classic tale of displaced art. Grand corporate art is so easily cast aside when progress demands it. When the wrecking balls finally arrived, the flute player was banished to a temporary employment agency lot in a neighboring suburb, and the giant steel sculpture was dismantled and dumped in a highway maintenance yard.

Why the wrecking balls? Well, fast forward to the 1990s. The regional district government bought this monument to modernity for forty-five million marks. They were thrilled. The district chief praised the move... until the building's stubborn realities caught up with him. The mid-century infrastructure was failing. The chief himself actually ended up trapped inside one of the original, highly temperamental 1964 elevators.

That tends to change a person's perspective on historic preservation.

Even though the building was a protected cultural monument, fixing it meant gutting the entire structure and replacing the famous glass facade. It was simply too expensive. So, despite fierce protests from heritage groups, the city voted for total demolition. By the end of 2024, the proud tower was completely erased from the Karlsruhe skyline, making way for a new, even taller high-rise.

The flute player is supposedly returning one day to a planned green space, but for now, the music has stopped. Let us keep moving toward the bustling Kriegsstraße, which is a seven minute walk from here.

Take a look at the wide, gray asphalt expanse stretching out before you, split by a solid concrete median and spanned by metal pedestrian overpasses. This is the Kriegsstrasse. Some roads are simply ways to get from A to B, but massive urban arteries like this one are living symbols of unending urban adjustment, constantly being ripped up and reshaped as a city tries to figure out what it wants to be.

Originally, around the year 1800, this road was built outside the old city gates for a very practical reason. It was meant to route marching armies around Karlsruhe and keep the citizens safe. Hence the name, Kriegsstrasse, which translates to War Street. But as the city grew, the street was swallowed up by urban sprawl. By the 1960s, city planners transformed it into a massive thoroughfare that in some spots swelled to ten lanes wide, creating a concrete river that effectively sliced Karlsruhe in half.

If you view the app, you can see a picture of the Ettlinger Tor intersection back in 2012, giving you a sense of the sheer surface congestion before the city decided to intervene.

By the early two thousands, the traffic had become unbearable. The city devised a highly ambitious project called the Kombilösung, or Combined Solution. The grand idea was to bury the cars in a 1,400-meter underground tube called the Karoline-Luise-Tunnel, and turn the surface into a pleasant, tree-lined boulevard with a green tram track.

Digging a massive trench through the heart of a city is rarely simple, and this project met some remarkably stubborn realities. Construction kicked off in 2017, plunging the area into noisy chaos. Then, in July 2020, disaster struck. A massive water pipe ruptured. Two hundred thousand liters of water cascaded into the brand new tunnel and tram tracks. It ruined every single electrical cable in the subterranean tube, completely wiping out six months of progress.

They pushed forward, eventually scheduling a grand opening ceremony for May 2022. The formal invitations were printed and ready to mail. But during a final safety test, a massive ventilation rotor detached from the ceiling and crashed to the tunnel floor. Naturally, the tunnel failed its safety inspection. The grand opening was scrapped, the street remained a chaotic construction zone, and local businesses, already starving for foot traffic, had to endure several more months of noise until the tunnel finally opened late that October.

Today, the surface is indeed greener, though locals still debate if the new, slightly sterile streetscape actually feels inviting. And about that name, War Street. In 2022, a mysterious activist group called the Pudelmützenbande, or Bobble Hat Gang, took matters into their own hands. They pasted over the word War on several street signs, temporarily turning this massive road into Peace Street. The city quickly peeled the stickers off, but it gave everyone a good chuckle.

Speaking of peace, let us leave the bustling traffic behind. It is time to head toward a much quieter spot nearby. Let us walk over to the Church of Peace.

Check the app to spot the Church of Peace that once stood here, a striking structure featuring a solid sandstone base, towering pointed-arch windows, and an intricate gothic entrance portal. In the late nineteenth century, the German Methodist community had a problem. Surrounded by massive state religions, independent congregations were often dismissed as obscure sects. To fight this prejudice, they needed to project permanence.

So, they commissioned an imposing, late-Gothic fortress. And who did they hire to design this bastion of respectability? A young architect named Hermann Billing. It was a fascinating choice, as Billing was an unpredictable pioneer of Art Nouveau, a decorative architectural style inspired by natural forms. He would soon scandalize the city by covering public fountains with naked nymphs and provocative caricatures. Yet, for 80,000 Marks, a substantial sum, Billing gave the Methodists the solemn sanctuary they desperately wanted.

The congregation loved it so much that after it was bombed in World War Two, they rebuilt it with their own hands. But grand survival stories often meet incredibly mundane ends. In 1968, the city bulldozed the church simply to widen the road for cars. The displaced congregation was forced to merge with another church nearby. In a perfect twist of fate, their new home was located at number eleven Hermann-Billing Street, named after the very architect whose unpredictable reputation they once ignored.

If you want to visit, their new church is open on weekends from nine to one. Now, let us walk toward the highest legal authority in the country, the Federal Prosecutor General at the Federal Court of Justice.

Look to your right, and you will spot a strict, geometric complex featuring a U-shaped main building, a striking semi-circular rotunda, and a towering five-meter-high concrete security wall. Your app features a photo of how this imposing modern fortress looks lit up at night.

This is the Federal Prosecutor General at the Federal Court of Justice. Put simply, this is Germany's state security hub. It serves as the absolute nerve center for federal justice, handling the nation's most critical cases of terrorism, espionage, and crimes against international law.

The building itself was designed by architect Oswald Mathias Ungers as a modern urban palace, finished in 1998. But a palace ringed by a massive security wall hints at the heavy burden carried inside. The chief prosecutor here is what Germans call a political official. That means they do not just enforce the law in a vacuum... they belong to the executive branch and must share the security and criminal policy goals of the current government. They take direct instructions from the Federal Minister of Justice.

As you might guess, blending the pure pursuit of justice with the demands of politics can get a little rocky. Take 2015, for example. The prosecutor at the time, Harald Range, opened a treason investigation against journalists who had published confidential intelligence documents. The Justice Minister hit the brakes and tried to stop a key report in the case. Range publicly accused the ministry of meddling with the independence of the judiciary. The minister's response? He immediately fired Range and sent him into early retirement.

But there is a much heavier shadow hanging over the early days of this institution. When West Germany was building its democratic legal system after World War Two, the high-minded goals of a fresh start collided head-on with a severe lack of untainted lawyers. A recent study revealed that in the 1950s, about 75 percent of the senior staff here were former Nazi party members. By 1966, ten of the eleven main federal prosecutors had Nazi pasts.

The most glaring example was Wolfgang Fränkel. In March 1962, he was appointed to the absolute top job as Federal Prosecutor General. Just months later, it was revealed that during the Nazi era, he had personally pushed for death sentences for minor, petty offenses. He was quickly ousted... but a later disciplinary hearing somehow concluded he had secretly opposed the Nazis. Unbelievably, that ruling allowed him to collect a generous state pension until his death in 2010.

The risks tied to this office are terribly real. In 1977, the reigning Federal Prosecutor, Siegfried Buback, was assassinated by the Red Army Faction terrorist group while simply being driven to work here in Karlsruhe. That shocking murder kicked off the German Autumn, a severe national crisis that tested the very foundations of the republic.

We are going to leave the intense world of federal law and national security behind us now. It is time to look at a very different kind of influence born here in Karlsruhe. Let us head toward our next stop, about a three-minute walk away, where we will dive into the wild early days of digital pioneering and the birth of a major internet giant called Web.de.

Notice the building on your right. This is the home of Web.de, a titan of the early German internet. Its origins are a classic tale of unexpected leaps. Back in the 1990s, this all started as a company making technical equipment for movie theaters. Enter the Greve Brothers. Matthias handled the business side, while Michael was the brilliant, tech obsessed nerd in the background, and together they pivoted their cinema tech company into a sprawling internet directory that went online in 1995.

During the dot com boom of the year 2000, a period of frantic investment in early internet startups, the web was expanding faster than anyone could organize it. Web.de was growing so relentlessly that they were desperate for hands on keyboards. Their solution to the staffing shortage was wonderfully blunt. They simply bought an entire advertising agency called Websolute, pulling all 45 employees into their ranks overnight just to acquire their talent.

But building an empire is very different from running one.

The brothers had a fierce grip on their creation. When they brought in an outside executive named Hans Wachtel to act as Chief Operating Officer, a role meant to streamline the business and rein in costs, the culture clash was spectacular. Wachtel wanted to outsource ad sales to save money. The Greve brothers, terrified of losing control, refused. Wachtel threw in the towel after just eight months, frustrated that a massive, publicly traded corporation was still being micromanaged like a garage startup.

This tight grip sometimes led to rather stubborn corporate realities. For years, the company faced harsh criticism from consumer advocates over some very aggressive tactics. Younger users, in particular, would receive an email wishing them a happy birthday with a digital gift box. A single click to open the gift would quietly enroll them in a premium club, which automatically turned into a paid subscription if they did not cancel in time. Unsurprisingly, German courts eventually had to step in and put a stop to the birthday traps.

There were also some wild misadventures in trying to expand. In 2002, they bought into a regional television network called B.TV. It was a complete financial disaster. The network went bankrupt within months, opening the door for the station to be bought by an eccentric media figure who turned it into a bizarre channel of esoteric call in shows.

But the most dramatic pivot of all belongs to Michael Greve. He poured massive resources into a project called ComBOTS, an ambitious software meant to combine email, text messages, and phone calls using animated comic avatars. It flopped disastrously, outpaced by simpler tools like Skype.

That failure became a profound turning point. Realizing that no amount of tech could stop the biological clock, Michael abandoned the internet entirely. He took over 300 million euros of his tech fortune and became one of the world's leading investors in rejuvenation biotechnology, funding research to literally cure human aging by repairing cellular damage. From sorting web links to fighting death itself, it is quite the career shift.

If you are here Monday through Friday between 8:00 AM and 6:00 PM, you will find the building open for regular business hours. For now, let us keep moving. We are heading toward the striking HfG building, leading us right to the Karlsruhe University of Art and Design, which is just about a four minute walk away.

You should be looking at a massive beige facade defined by a strict repeating grid of large industrial windows, topped with a classical triangular pediment featuring a distinct round window.

You are standing in front of the Karlsruhe University of Art and Design, housed within a structure known as Hallenbau A. This colossal industrial building was designed by the architect Philipp Jakob Manz and finished just before the end of the First World War, originally purposed to mass-produce weapons. It carries a heavy, dark history. By the Second World War, this weapons and munitions factory had swelled to the size of a small town, employing up to thirty thousand workers. Inside these very halls, thousands of forced laborers from across Europe were made to produce armaments for the Nazi regime under horrific conditions.

But decades later, a profound shift took place. In 1992, art historian Heinrich Klotz founded this university with a grand vision to create an electronic Bauhaus. The Bauhaus was an influential early twentieth-century German design school that famously combined crafts and fine arts, and Klotz wanted to update that concept for the digital age, merging traditional art with media technology.

Moving the school into this building in 1997 was an act of radical reinvention. It was a conscious moral umwidmung, a German word that means a formal repurposing or rededication. The founders took a space historically dedicated to the mass production of death, and turned it into a laboratory for creativity. Where artillery shells were once manufactured, students now design digital art, film, and scenography.

Yet, even the most visionary artistic utopias have to deal with human nature. Over the past decade, the university became the stage for bitter internal power struggles. A nationwide scandal erupted when an assistant to the rector rose to a prominent position in a right-wing populist political party. The academic world was outraged, leading to his swift removal from leadership duties. But the drama did not stop there. Rectors came and went, their ambitious reform plans repeatedly crashing into stubborn institutional resistance. The peak of this chaos came recently with a Belgian rector named Jan Boelen. After being voted out of office, Boelen sued over procedural errors, won his case in court, and triumphantly returned to his desk... only for the professors to immediately hold another vote and oust him again, this time by a crushing margin of nine to one.

Grand ideals are beautiful things, but they always have to survive the messy reality of the people trying to build them. Take a moment and look closely at the colossal scale of the Hallenbau. Can you sense the ghosts of its industrial past hiding behind the modern art installations?

Feel free to explore the public areas of this fascinating art hub. Whenever you are ready, we will head to the Städtische Galerie Karlsruhe, which is just a short three-minute walk away.

Notice the massive beige structure characterized by a prominent triangular roofline and a relentless grid of large, multi-paned industrial windows.

This is the Kunstmuseum Karlsruhe, historically known as the Städtische Galerie. We are actually looking at another wing of Hallenbau A, that colossal former munitions factory we encountered earlier. But inside this tough steel and concrete shell is a remarkably delicate world. It holds a staggering collection of modern and contemporary art.

Getting this museum established was an uphill battle. For decades, the city's art collection was essentially displaced art. The city had grand cultural visions, but the stubborn reality of wars and tight municipal budgets kept getting in the way. Early collections bounced from one temporary home to another. They survived a devastating nineteen forty two bombing that wiped out a huge chunk of early acquisitions, and for years, priceless works were just hung haphazardly in random city office buildings.

The museum's ultimate success came from a very unexpected pivot. It was not born from a massive government grant, but from a quiet personal friendship.

Enter Ute and Eberhard Garnatz.

Eberhard was a lawyer and business executive from Cologne. In the nineteen seventies, he and his wife fell completely in love with contemporary German art. But they were not eccentric billionaires with unlimited funds. When they started buying, they literally put fine art on layaway. Once, at an art fair, they bought pieces in installments because a painting they desperately wanted cost a hundred thousand German marks, which completely blew their budget.

Buying piece by piece, paying over time, they quietly amassed an incredible collection of around seven hundred works. We are talking about heavy hitters of the art world, including icons like Sigmar Polke and Georg Baselitz.

In nineteen ninety six, Eberhard, who had become good friends with Karlsruhe city officials, made an astonishing offer. Based purely on that personal trust, the couple handed their entire life's passion over to this museum on permanent loan.

Today, art experts value the Garnatz collection at around forty million euros. Eberhard later looked at the exploding art market and joked that if they had to start over today, they could never even afford to buy their own collection. It is a monumental civic treasure, secured simply because some people trusted each other.

If you want to wander through and see these masterpieces yourself, the museum is open Wednesday through Sunday from late morning to early evening.

For now though, we are going to pivot from the quiet contemplation of fine art to the gritty, modern challenges of keeping massive industrial facilities running. Follow your map for a short three-minute walk to our final stop, the Big Bechtold Group.

Here is a geometric, flat-roofed building defined by its wide rows of windows and the prominent lowercase big dot logo near the main entrance.

This is the headquarters of the Big Bechtold Group. Back in 1981, Bernd and Gisela Bechtold laid the foundation for this company as a modest little engineering office focused on electrical planning. But cities are complicated beasts. Grand civic plans often run face-first into stubborn, messy realities, and surviving in business usually requires constant adaptation.

As Karlsruhe expanded, the Bechtolds realized that constructing buildings was only half the battle. Somebody had to keep the lights on, the floors clean, and the doors locked. So, they evolved into a massive facility management and security empire.

Consider a very modern headache. Today, cities are pushing hard for green energy, rolling out fleets of electric vehicles. It is a noble ambition. The stubborn reality? Thieves keep sneaking into charging parks to steal the expensive copper cables right out of the stations. To stop this, Big Bechtold deployed something called smart video towers. These are mobile camera systems powered by artificial intelligence. If the software spots someone tampering with a cable, it alerts a central control room. A security guard can then intervene directly over a loudspeaker, coordinating a response before the thief even knows what happened.

In 2013, the founders handed the reins to their daughter, Daniela Bechtold-Schwabe. As an industrial engineer, she brought a fierce, values-driven approach to the family business, and she was not afraid to call out political absurdity. When the government mandated higher minimum wages, she publicly criticized the hypocrisy of large public agencies who demanded the wage hikes for workers, but flatly refused to adjust their existing contracts to reimburse the service companies for those exact increased costs.

She also tackled the chronic shortage of skilled workers with her own pragmatic pivot. Recognizing that traditional childcare hours were useless for shift workers, she bypassed the usual systems entirely. The company founded its own youth welfare non-profit and opened a corporate daycare called Schlossgeister. Designed specifically for working parents, it stays open from seven in the morning until six in the evening, closing just twelve days a year.

Today, they are even testing autonomous delivery robots to keep the urban arteries of tomorrow flowing smoothly. Unsurprisingly for an organization that never really sleeps, this facility operates open twenty four hours a day, seven days a week.

Take a quiet moment here to look around the street before we wrap up our journey together with a final reflection on everything we have seen.
