ピッツバーグ・オーディオツアー：ダウンタウンの鉄鋼の巨人と文化の宝

Look to your left at the 410-foot skyscraper featuring a diamond-patterned, dark grey aluminum facade and a flat, stepped-back roofline.

We just marveled at the U.S. Steel Tower, and now another mighty Pittsburgh metal takes center stage. This thirty-one story building beside Mellon Square is the Regional Enterprise Tower, originally famous as the Alcoa Building.

Completed in 1953, it was the first skyscraper ever built with an all-aluminum facade! The walls are an astonishing one-eighth of an inch thick. Check the image on your device to see a vintage shot of this groundbreaking metal skin shortly after it was built. It was an engineering marvel. They designed the windows to rotate a full 360 degrees to be washed from the inside. A unique heating and cooling system was hidden in the ceiling, eliminating clunky radiators and freeing up fifteen thousand square feet of extra space. If you want to see how this iconic modernist fixture has stood the test of time, check out the before and after slider in your app.

Before this metal giant stood here, the site housed pure theatrical magic. From 1903 to 1950, this was the Nixon Theater. It was a gorgeous Beaux Arts structure... a highly decorative French classical architectural style crowned with a massive dome. Opening night critics called it the world's most perfect playhouse. The interior dripped with luxury, featuring imitation marble columns capped in solid gold and walls styled like damask silk. The productions were wonderfully extravagant. A 1905 staging of Ben Hur featured four live horse-drawn chariots, while another play brought in a herd of camels, horses, goats, and fifty camel drivers!

When Alcoa bought the theater in 1950, people were outraged. Legendary actress Katharine Hepburn wrote a furious letter to the city before demolition, arguing the new skyscraper would just be another building... maybe fascinating, but not glamorous. Today, the top floors have been converted into apartments, keeping its legacy alive.

Enjoy the view of this aluminum marvel, and let's keep moving when you are ready.

Look to your left and you will see a massive red brick building resting on an elegant light stone base, defined by three towering vertical sections connected by dramatic arches near the roofline. You are standing in front of the Omni William Penn Hotel.

I am so thrilled to share this place with you. Built between 1915 and 1916, this twenty three story marvel originally cost six million dollars to construct, which is roughly one hundred and eighty million dollars today. When its doors opened on March 11, 1916, newspapers across the country declared it the Grandest Hotel in the nation. The opening night gala was the biggest party Pittsburgh had ever seen, hosted by the United States Secretary of State.

If you step inside today, you can still visit the Terrace Room, a gorgeous restaurant dating all the way back to that opening year, complete with a wall length mural depicting the taking of Fort Pitt. But the stories that echo through these halls are what make it truly legendary. Imagine the sheer chaos in April 1970 when the local zoo president addressed a rotary conference inside alongside an eight month old elephant named Rani, a llama, an eagle, and a snapping turtle. Or picture the romance of 1934, when a young Bob Hope dropped to one knee and proposed to his wife right here. The brilliant hotel staff even invented the famous bubble machine later popularized by bandleader Lawrence Welk.

In 1929, an ambitious owner named Eugene Eppley financed a massive expansion that filled the entire city block. Take a glance at your app to see the magnificent interior of the grand lobby, capturing the sheer scale of the space. This expansion made it the second largest hotel in the entire world, bringing the room count to a staggering sixteen hundred. It also added a spectacular Art Deco ballroom at the very top, full of the glamorous geometric shapes and sleek lines that made the 1920s style so popular.

Music lovers, this spot is sacred ground. In the winter of 1937, the legendary Count Basie and His Orchestra held a residency in the hotel lounge called the Chatterbox. The live radio broadcast from that room became the first known recording of the Basie band with jazz icons like Lester Young and Buck Clayton. The swing music pouring out of those doors must have been absolutely electric.

Over the decades, this hotel has hosted luminaries like John F. Kennedy, as well as Harry S Truman and Dwight D. Eisenhower, who both actually stayed here during the intense heat of their 1956 presidential campaigns. If you look at the second picture on your phone, you can see how the grand building illuminates the skyline, serving as a shining beacon of Pittsburgh history. Today, it remains a proud and award winning member of the Historic Hotels of America.

Take your time admiring the grand exterior, and head to the next stop whenever you're ready.

Look to your right for a raised urban plaza featuring low, square concrete planters, striking geometric pavement, and neat rows of trees. Welcome to Mellon Square! This is not just any park, it is a brilliant piece of engineering. Back in 1953, it became the very first Modernist park built completely over an underground parking garage.

Remember that gleaming aluminum skyscraper we admired a few minutes ago, the Regional Enterprise Tower? After World War Two, the Aluminum Company of America wanted to pack up and move their operations to New York. But a powerhouse banker named Richard King Mellon stepped in. He convinced them to stay by proposing that shiny new headquarters, and as a massive sweetener, he promised them this magnificent plaza right across the street. The Mellon family poured four million dollars into creating it, which is over forty-five million in today's money!

But the ground beneath these black, white, and green tiles holds even older stories. Take a look at your screen to see a bronze historical marker located in the square. In 1881, right here in a building called Turner Hall, the world's very first labor union was founded, eventually becoming the American Federation of Labor, a massive national union coalition. And forty years later? The very first live radio broadcast of a theater performance went out to the world from a stage on this exact block.

If the space feels a bit cinematic to you, you might recognize it from the 2002 thriller The Mothman Prophecies. When the park opened, its nine massive circular bronze fountain basins were the absolute largest ever cast, and you can check your app for a close-up of the beautiful water feature.

The square is open every day from six in the morning until eleven at night for you to enjoy. Take a moment to soak in this historic oasis. Whenever you are ready, we can wander over to our next stop.

Look to your left and spot the striking Trinity Cathedral, a tan stone structure featuring classic Gothic pointed arches and a distinctive, towering central spire with a clock face.

This land holds incredible historical weight! Long before European settlers arrived, this terrace above the rivers was sacred to Native Americans as a burial ground. Later, heirs of Pennsylvania's founder, William Penn, actually deeded this very plot to the congregation. Because of this layered history, the churchyard holds the oldest marked graves west of the Atlantic Seaboard, serving as the resting place for Native American leaders alongside French, English, and American colonists.

The congregation itself evolved dramatically over the centuries. They started in the 1780s two blocks away in a brick, eight-sided meeting house literally called the Round Church. By 1824, they moved here and built what is considered Western Pennsylvania's first Gothic structure.

The beautiful building before you is their third home, completed in 1872 by architect Gordon W. Lloyd. Look at the image on your device to see a clear view of that central steeple. This English Gothic style was incredibly popular with mid-Victorian Episcopalians, a Christian denomination that is part of the worldwide Anglican communion. Inside is a soaring central hall known as a nave, lined with clustered stone columns. While most of the stained glass dates back to 1872, a 1967 fire destroyed several windows, which were then replaced with stunning medieval-style glass.

You might notice the exterior stonework looks remarkably well-preserved. Up until 2007, it was covered in thick industrial soot from Pittsburgh's famous steel-making era. That grime was actually causing acid runoff to eat away at the stone before they finally scrubbed it clean!

The cathedral also navigated a complex modern chapter during a major 2008 theological split, or schism, within the diocese. For three years, Trinity miraculously maintained ties with both the breakaway and continuing factions, until officially reaffirming its Episcopal identity in 2011.

If you want to view the interior, they are open Tuesday through Friday from ten to three, and Sunday mornings. Trinity Cathedral remains an enduring monument to faith, survival, and community. Take all the time you need, and whenever you are ready, we will head over to our next stop.

Over on your right, you are looking at the site of a genuine lost giant of Pittsburgh. Back in 1912, if you craned your neck up right here, you would be staring at the tallest building in the entire city. The First National Bank Building started as a modest high-rise in 1909, but just three years later, it was expanded into a massive 26-story, 118-meter skyscraper.

Imagine the buzz on April 1, 1912, when the very first tenants proudly moved in. The building heavily advertised its state-of-the-art fireproofing. In an era where devastating urban fires were a terrifying threat, that promise of safety was the ultimate luxury.

But stone and steel don't always last forever. By the late 1960s, Pittsburgh National Bank decided it was time for a modern upgrade. Tenants were told to pack up and vacate the building by April 30, 1968. Work began later that year, and the structure was completely demolished in 1969 to clear the way for One PNC Plaza. It is wild how an entire skyline-defining titan can simply vanish.

Take a moment to picture that historic giant. Whenever you are ready, let's wander to our next stop.

Look to your left and you will see a towering glass skyscraper defined by its sleek rectangular shape and a distinctive dark sloped roofline at the very top. This is the Tower at PNC Plaza, a spectacular structure soaring thirty three stories and five hundred forty five feet into the Pittsburgh skyline. PNC and its predecessors have proudly called this exact intersection of Fifth Avenue and Wood Street home since 1858.

When they announced this four hundred million dollar project in 2011, they set out to build the greenest office tower in the world. You can witness the dramatic rise of the Tower at PNC Plaza, transforming from an early construction site in 2012 into a gleaming, glass-enclosed skyscraper by 2015 right in your app. That construction phase alone created twenty five hundred temporary jobs, and PNC purposely directed twenty percent of the budget to women and minority owned contractors to help build up the community.

The technology inside this building is basically science fiction brought to life. It features the country's only fully automated double-skin facade. That means the building is wrapped in two separate layers of glass with a thirty inch gap in between. Fresh air enters through small, automatically programmed vertical exterior windows playfully called poppers. Inside, automated louvers called floppers open up to let that fresh air circulate naturally. Office workers can literally slide open wood-framed glass doors and step out onto a built-in porch for a breeze.

And remember that sloped roof we looked at? That is not just for style. It is the largest solar chimney in a modern American office building. It acts as a five thousand square foot glass box angled south toward the sun. As the sun heats the air inside, it naturally rises and exits through the roof, pulling fresh air up through the entire building without relying on massive, energy-hogging electric fans. Because of this, the tower's climate control operates in a net zero energy state, meaning it produces as much energy as it consumes, for up to thirty percent of the year!

They even built a water recycling system that treats rain and wastewater, cutting down their clean water use by an astonishing seventy seven percent. Take a look at your screen to step inside the Tower at PNC Plaza's lobby and experience The Beacon, a thirty foot sculptural installation visualizing the building's real-time energy performance. This absolute masterpiece of design achieved LEED Platinum certification, surpassing the absolute strictest environmental requirements for green architecture.

If you need to visit for business, the building is open Monday through Friday from 9 AM to 5 PM, though it is closed on Saturdays and Sundays. Take a moment to really look up and appreciate this marvel of modern sustainability. When you are ready, we can head to the next stop.

You should be looking at a modern, light tan stone complex featuring large rectangular openings that form an open air balcony, marked by a sleek, vertical black sign spelling out Pittsburgh Playhouse. Check the first image on your screen to see the full sweep of this gorgeous modern structure.

Let me tell you, the drama that happened inside this institution rivals anything ever performed on its stages. It all started back in 1933 as a humble community theater. But they quickly ran into debt, so they brought in a man named Richard S Rauh. He was the heir to a massive men's clothing fortune, but his true passion was the arts. While spending time in New York, Richard fell madly in love with a radio actress named Helen Wayne. He was totally smitten. He actually promised to build her a stage to act on if she would just stay in Pittsburgh with him. The couple married in 1935, and Helen went on to star in thirty eight productions at the Playhouse.

For over seventy years, their artistic home was not here, but in a rambling set of buildings on Craft Avenue, which you can see in the second image on your app. That old location even had a basement restaurant with an ice cream parlor and a meat locker!

But that golden age hit a major wall in the 1960s. Enter William Ball, a visionary director who wanted to turn this beloved community theater into a fully professional powerhouse. He staged incredibly ambitious, highly controversial plays. The local supporters, who loved light comedies starring their favorite community actors like Helen Wayne Rauh, were absolutely outraged. Ball lost his backing and left for San Francisco. You would think the board learned their lesson, right? Well, the very next director brought in even more controversial shows! Subscriptions plummeted, causing a massive financial crisis. They had to launch an emergency campaign to raise three hundred thousand dollars, which is over two point eight million dollars today. Even with the money, the board was so fractured that eight directors flat out resigned.

The Playhouse was on the brink of total collapse until Point Park University stepped in and acquired it in 1968, eventually moving it to this stunning downtown complex in 2018.

I just love how they honored the past when they built this place. To clear space for this massive building, they had to remove three turn of the century buildings, which made preservationists incredibly worried. But they salvaged the historic terra cotta facades. Terra cotta is a type of baked clay often used for beautiful, intricate architectural decorations. They carefully deconstructed those clay facades and built them right into an outdoor plaza. They even connected the theater to the historic 1903 Pittsburgh Stock Exchange building next door, restoring its gorgeous stained glass skylights.

Today, this complex has three distinct stages, including a ninety nine seat black box theater, which is just a simple, unadorned square room painted entirely black to allow directors total creative freedom. Naturally, it is named the Rauh Theatre, honoring the family whose romance helped start it all. It is a brilliant mix of Pittsburgh's architectural history and its vibrant creative future. Appreciate the details of this restored facade, and we'll move on when you're ready.

On your left, you will spot a massive, seven-story rectangular block of light stone masonry, topped with a distinctive dark cornice, the decorative ledge lining its flat roof.

This is the Frank and Seder Building! The story starts with Isaac Seder and Jacob Frank, two Russian Jewish immigrants who chased the American dream right here in Pittsburgh. They began selling women's wear wholesale in the early nineteen hundreds, then pivoted to retail, opening a booming downtown department store in nineteen oh seven.

They expanded, but then disaster struck. On January twenty seventh, nineteen seventeen, a massive fire ripped through this district. The original store was completely reduced to ash, causing six hundred thousand dollars in damage, which is over fourteen million dollars today! But Isaac and Jacob did not quit. They immediately rebuilt, and by nineteen eighteen, the thirty meter tall structure standing before you was finished. Glance at your screen. That is a nineteen twenty seven snapshot showing the grand department store at its absolute peak.

The brand became a giant, expanding across several states. It had its rocky moments, including intense, sometimes violent labor strikes in the nineteen fifties, before eventually closing its doors in nineteen fifty eight. Today, after developers abandoned plans to tear it down for a towering skyscraper, it is being reborn as Smith and Fifth, blending modern apartments, retail, and office space inside its historic shell.

It is amazing how this survivor just keeps reinventing itself for a new generation. Let's follow the route to our next piece of history when you're set.

Look right toward the modern Kaufmann's expansion. This was once the site of the Carnegie Building, a massive rectangular high-rise featuring a pale stone base, tall brick upper floors, and a bold overhanging roof cornice. Completed in eighteen ninety-five, this was Pittsburgh's very first steel-framed skyscraper, and the tallest in the city at the time.

It was designed in the Chicago school architectural style, a revolutionary method that used a rigid internal steel cage to hold up the building rather than relying on heavy exterior walls. This made it one of the first steel-skeleton structures in the world!

This Fifth Avenue landmark served as world headquarters for the Carnegie Steel Company, run by industrialist Andrew Carnegie. His empire eventually became U.S. Steel, whose massive modern tower we admired earlier. Sadly, this thirteen-floor beauty met the wrecking ball in nineteen fifty-two to make room for an expansion of Kaufmann's flagship store.

Take a moment to reflect on this lost piece of history. Let's continue on whenever you're prepared.

Look to your right for a massive structure of rough-cut granite blocks, featuring a steep red tile roof and a towering five-story stone spire reaching into the sky. Welcome to the Allegheny County Courthouse, a true architectural masterpiece.

When Boston architect Henry Hobson Richardson finished designing this complex in the 1880s, he called it his great achievement. And you can completely see why. It is one of the finest examples of Romanesque Revival architecture in the country. If that term is new to you, Romanesque Revival is a style known for heavy, stable appearances, using wide arches and thick, rusticated stone. Rusticated just means the granite blocks were left with a rough, natural-looking texture instead of being polished smooth.

But this is actually the third courthouse to stand in Pittsburgh. The second one sat right on this very spot, on Grant's Hill. It was a beautiful Greek Revival building, a style inspired by ancient temples, made of polished gray sandstone, but it had a fatal enemy... Pittsburgh's infamous coal smoke. The corrosive smoke literally ate away at the stone facade until the heavy stone cornices started dropping right off the building. Then, a massive fire finished the job in May of 1882.

When Richardson won the competition to build the replacement, he wanted a space that felt dignified but also breathable. Take a look at your screen to see what I mean. He built the courthouse around a stunning interior courtyard, which allowed fresh air and natural sunlight to pour into almost every room.

There is a really funny quirk about the entrance, though. In the 1900s, the city decided to lower the street level in front of the building as part of a massive re-grading project. Richardson actually anticipated this, so he buried finished masonry underground, knowing it would eventually be exposed. A grand stairway was added to reach his original ceremonial entrance, but during a street widening project in the 1930s, those stairs were ripped out. So today, visitors actually enter the building through low corridors that used to be the basement.

If you walk around to the Ross Street side of the complex, you will spot an enclosed stone walkway arching over the street. Check your app for a great view of it. That is the Bridge of Sighs, modeled directly after the famous bridge in Venice. It connects the courthouse to the former county jail. The jail itself is fascinating. In the 1990s, instead of tearing it down, the county spent twenty five million dollars transforming the old cell blocks and rotunda into the Family Court division, a brilliant piece of historic preservation.

The building is so incredibly cinematic that Hollywood loves it, using it as a backdrop for movies like Hoffa and Striking Distance. If you want to peek inside at the stunning 1930s murals by Vincent Nesbert, the building is open to the public Monday through Friday from 8:30 AM to 4:30 PM, though it is closed on weekends. Catch your breath, and follow your map to the final stop.

On your left stands the monumental Pittsburgh City-County Building, a massive pale gray stone structure defined by three deep arched entrance bays at the base and a striking row of tall columns lining the upper floors.

This is a spectacular powerhouse of a building. By the early twentieth century, Pittsburgh was growing so fast it was practically bursting at the seams. In nineteen oh seven alone, the city absorbed neighboring Allegheny City, adding a hundred and thirty thousand new residents in an absolute flash. The old city hall simply could not handle the crushing crowds, so city and county officials teamed up to build this masterpiece.

And they wanted it to be entirely homegrown. Mayor Joseph Armstrong was fiercely protective of his city. He demanded that every ounce of material and every single laborer come straight from Allegheny County. Even the design competition was strictly limited to local architects, eventually won by a team led by the brilliant Henry Hornbostel. You can see the grand portico they designed right on your app.

But the project almost derailed before a single shovel hit the dirt. A local contracting firm filed a legal injunction to halt the work, furious over what they claimed was an improper, shady bidding process for the supervising engineer. The legal battle completely paralyzed construction for over a year. The dispute went all the way up to the Pennsylvania Supreme Court and required a special legislative act to finally resolve. When they eventually broke ground in nineteen fifteen, they were so relieved that the pick and shovel used in the ceremony were silver plated and proudly displayed as trophies in the office of the Mayor.

Hornbostel designed the building in the Beaux Arts style, filling the massive, symmetrical structure with rich classical decorations. It was also heavily influenced by the City Beautiful Movement, an urban planning philosophy that believed creating sweeping, orderly civic centers would inspire civic virtue and elevate society. If you want to see how the surrounding streetscape has evolved while this monumental structure stayed completely steadfast, swipe to the before and after view on your screen.

While the outside is intensely rigid, the inside is pure magic. The Grand Lobby is a naturally lit atrium boasting a breathtaking forty seven foot barrel vaulted ceiling. Holding up that magnificent ceiling are custom bronze columns crafted by the legendary Louis Tiffany Studios, featuring intricate carvings of the Native American frontiersman Guyasuta and the historic Fort Pitt Blockhouse at their bases. Even the elevator doors are storytelling masterclasses, covered in bronze reliefs that depict the evolution of Pittsburgh's municipal buildings, aging from childhood to adulthood as the architecture scales up. Hornbostel was so dedicated to his complete vision that he even custom designed the furniture for the Mayor's office and the Supreme Court room... and it is all still being used today.
