プラハ・オーディオツアー：旧市街広場の時計仕掛けの伝説

To your left rises a dramatic Baroque monument characterized by its undulating white façade, a central dome weathered to a pale green, and twin towers that frame the entrance. This is the Church of St. Nicholas, but do not let its confident, pious appearance fool you. If buildings could have identity crises, this one would be in therapy. While it looks like a permanent fixture of the square, the structure you see was only completed in 1737. It was designed by Kilian Ignaz Dientzenhofer, the heavy hitter of Prague Baroque architecture, to replace a burned-down Gothic church that had stood here since the 1200s. The Benedictine monks moved in, expecting to stay forever. They were wrong. Just fifty years later, Emperor Joseph II decided he had too many monasteries and not enough cash. He deconsecrated the church and kicked the monks out. What followed was essentially a massive yard sale. The altars, paintings, and bells were sold off to the highest bidder. Local legend says one of the bells went to a village called Dolany, while a statue ended up guarding a bridge in a town called Přeštice. That poor statue actually fell into the river in the 1980s, which seems to be just the sort of luck associated with this place. Once the church was stripped, the city bought the empty shell and turned it into a warehouse. During the Napoleonic Wars, instead of incense and prayers, the nave-the soaring central hall of the church-was filled with sacks of grain. It served as a military supply depot, which is a fairly humble comedown for a Dientzenhofer masterpiece. Its fortunes turned again in 1870 when it was leased to the Russian Orthodox Church. This brings us to the most impressive artifact inside. If you peek in, look for the massive crystal chandelier. It is shaped like an imperial crown and weighs fourteen hundred kilograms-that is roughly the weight of a compact car hanging from the ceiling. It was a gift from the Russian Tsar Nicholas II to the Orthodox congregation here. History kept moving. We just came from the monument to Jan Hus, and his legacy actually circles back here. In 1920, this building became the birthplace of the Czechoslovak Hussite Church, a modern denomination that broke away from Rome, led by a man named Karel Farský. Despite the years of abuse and being treated as a storage locker, the artistic soul of the building survived. The ceiling frescoes by Kosmas Damian Asam, depicting the lives of saints and scenes from the Old Testament, are stunning. They were once whitewashed over-perhaps to match the grain sacks-but have since been restored. From a Benedictine jewel to a grain silo, a concert hall, a Russian outpost, and finally a Hussite church, St. Nicholas has proven to be the ultimate shapeshifter of Old Town Square. St. Nicholas stands as a testament to Prague’s ability to reinvent itself, no matter how many times the furniture gets sold. Take a moment to admire the curves of the façade, and when you are ready, we will continue our walk.

Look to your right and locate the intricate medieval structure on the tower wall, defined by two massive circular dials stacked vertically and flanked by dark gothic statues. You are standing in front of the Prague Orloj, the oldest astronomical clock in the world that is still in operation. It is a masterpiece of medieval engineering that functions as much more than a simple timekeeper. Think of it as a primitive planetarium or a mechanical astrolabe-a complex tool used by astronomers and navigators to calculate the position of the sun, moon, and stars. The oldest parts of this mechanism date back to 1410, created by a clockmaker named Mikuláš of Kadaň and a mathematics professor named Jan Šindel. Let’s decode that upper dial, the astronomical one. It is designed to show the state of the universe. The background represents the Earth and the sky; the blue center is the Earth itself, the upper blue is the sky above the horizon, and the black area is night. The golden sun arm sweeps across this background to tell you the time in three different ways simultaneously. First, the golden hand points to Roman numerals for our standard local time. Second, the position of the sun on the curved golden lines shows "unequal hours." In the medieval mind, an hour wasn't fixed; it was simply one-twelfth of the daylight, meaning hours stretched longer in summer and shrank in winter. Finally, the outer ring with the gothic numbers marks Old Czech Time, which counts the hours passed since sunset. It is also a theater of morality. Look at the four figures standing on either side of that upper dial. These represent the anxieties of medieval citizens. On the far left, you have Vanity, a figure admiring himself in a mirror. Next to him is a Miser holding a bag of gold, representing greed. On the far right is a figure representing earthly pleasures. But the most important character is the skeleton standing next to the Miser. That is Death. Every hour, he rings his bell and inverts his hourglass. The other three figures shake their heads side to side, signaling that they are not quite ready to go yet. Above them, two small windows slide open to reveal a procession of the Twelve Apostles peering out at the square. For centuries, a legend persisted that this clock was built later, in 1490, by a master named Hanuš. The story goes that the city councilors were so possessive of their beautiful clock that they ordered Hanuš to be blinded so he could never recreate his work for another city. In retaliation, the blind master supposedly reached into the gears and destroyed the mechanism, silencing the clock for a hundred years. While it makes for a dramatic tale, historical records corrected this in the 20th century, confirming the original 1410 creation date. The clock has survived real violence, however. In May 1945, during the Prague Uprising, Nazis fired on this tower from armored vehicles. The wooden sculptures burned, and the calendar dial-the large circle at the bottom-was heavily damaged. It was painstakingly restored, but the drama didn't end there. In 2018, during a major renovation, a painter named Stanislav Jirčík was hired to restore the calendar dial. A local heritage group later noticed that the figures didn't look right. The painter had radically changed the faces, ages, and even genders of the characters, allegedly painting in the likenesses of his own friends as a joke. The deputy mayor called the work "botched" and "banal," a rather harsh review for a piece of public art. Take a moment to watch the gears and figures if you like. When you are ready, we can continue on to the Old Town Hall just a few steps away.

Look to your left at the massive beige stone tower rising high above the square, attached to a distinctive pink building with ornate dark windows. You are standing before the Old Town Hall, but to call it a single "building" is actually a bit misleading. It is really more of an architectural Frankenstein’s monster, stitched together over centuries. Back in 1338, the city councillors decided they needed a headquarters. But rather than building something new from the ground up, they simply bought a large patrician house from a local clan called the Volflin family. As the city grew, the councillors played a real-life game of Monopoly, gradually buying up the neighboring properties-the Mikeš house, the Cockerel house, the "Minute" house-and knocking down walls to connect them all. That is why the architecture looks a bit disjointed; it is a row of separate lives forced to work together as one institution. The most prominent feature is, of course, that massive square stone tower. It was finished in 1364 and stood as the tallest structure in the city throughout the Middle Ages. If you look at the dark, projecting bay window on the corner of the tower, you are looking at the Town Hall Chapel. It is a stunning piece of Gothic architecture. If you could float up there and inspect the stonework on the columns, you would see a repeating emblem: a kingfisher bird and the letter "E" inside a twisted wreath, technically known as a torse. These were the personal symbols of King Wenceslas IV, marking the work as a royal project. It was the King’s way of autographing the building. Scan your eyes down to the facade of the buildings attached to the tower. You might spot a window from the 1520s bearing the Latin inscription "Praga caput regni," which translates to "Prague, the capital of the kingdom." It sits on a high cornice, supported by brackets and pilasters-those are flattened columns built into the wall for decoration rather than support. It is a bold declaration of the city's importance, etched right into the stone for everyone to see. Inside this complex, the architecture is just as impressive, particularly in the old council chamber. It has a beautiful wooden coffered ceiling-meaning it has a grid of sunken panels-dating from around 1470. But my favorite detail is a bit darker. There is a wooden sculpture of a suffering Christ from the early 1400s, positioned right where the councillors sat. It bears the inscription "Judge justly, O Sons of Man." It was placed there intentionally as a heavy-handed warning to the politicians: do your job honestly, or face the consequences. Nothing like a little divine pressure to keep a city council meeting on track. However, the building is not whole. If you look to the side, you will see a scar where a wing once stood-a result of the Second World War which we will investigate in the next stop. When you are ready, let's step closer to look at that missing piece.

From this angle, take a closer look at the beautiful, protruding bay window on the tower known as an oriel. This oriel belongs to the Chapel of the Virgin Mary, consecrated in 1381. It was built by the workshop of Peter Parler, a famous master builder whose name you might hear quite a bit in this city. Inside the tower, above the chapel, there was once a bell used to summon the council, which had a rather dramatic end. That brings us to the darker chapter of this landmark. In May 1945, during the final days of World War II, the Old Town Hall became a headquarters for the Czech resistance during the Prague Uprising. On May 8th, mere hours before the German surrender was signed, the building came under heavy shelling from German tanks. A massive fire broke out. The destruction was catastrophic. The bell I mentioned crashed down from the tower and melted from the intense heat. A precious city archive, documenting centuries of Prague’s history, was turned to ash. The fire completely destroyed a large Neo-Gothic wing that used to stand on the north side of the complex. If you look at the site today, you might notice an open space or park area where a building seems like it should be. That gap is a scar from the war. Since the late 19th century and continuing well after the fire, there have been at least eight different architectural competitions to design a replacement for that wing. Architects have argued over it in 1905, 1947, 1966, and even 1988. Yet, every single competition either ended without a winner or produced a design that was never built. It seems the city simply cannot agree on how to fill the void, so the space remains empty. More recently, between 2017 and 2018, the surviving tower and facade underwent a massive renovation costing a fortune to restore their authentic look, ensuring that what remains of this patchwork complex stands strong. It is a resilient witness to the city's turbulent past, wearing its history in its mismatched architecture. When you are ready, we can head to the next stop.

Look for the massive fortification made of blackened sandstone blocks, rising to a high, steep slate roof crowned with four corner turrets and golden spires. You are standing before what is arguably one of the most beautiful Gothic gateways in Europe. This is the Old Town Bridge Tower. It wasn’t just designed as a defensive fortification; it was built as a triumphal arch, a symbolic curtain-raiser for the coronation processions of Czech kings as they moved from the Old Town across the river to the castle on the hill. Emperor Charles IV commissioned this masterpiece in the mid-fourteenth century. He hired Peter Parler, the same brilliant architect-or master builder-who created the soaring choir of St. Vitus Cathedral. Parler was a true polymath, skilled in sculpture and engineering, and he poured that genius into this stone. If you look at the decoration on the eastern side facing the Old Town, it is actually a diagram of the medieval universe. It is divided into spheres: the earthly world of commoners at the bottom, the royal sphere in the middle with statues of Charles and his son Wenceslas IV, and the heavenly sphere at the top protected by saints. There is a hidden layer of magic here, too. Charles IV was obsessed with numerology and astrology. For instance, there are exactly twenty-eight decorative stone elements, known as crabs, on the lower arch, representing the twenty-eight days of the lunar cycle. Above them, twenty-four more represent the hours of the day. The architecture is actually a calendar. If you were standing here on the summer solstice, the twenty-first of June, at noon, you would see the shadow of a stone lion head fall perfectly onto a stone eagle. It is a celestial alignment that only happens once a year, symbolizing the union of the Bohemian and Roman legacies. However, this tower has witnessed horrors that contrast sharply with that golden symbolism. In the early seventeenth century, the mood in Prague shifted from glory to tragedy. After a failed Protestant uprising against the Catholic Habsburg dynasty, twenty-seven Czech lords were executed in the Old Town Square in 1621. To send a brutal message, the executioner placed the severed heads of twelve of those men into iron baskets and hung them from the gallery of this very tower. They didn’t just leave them there for a week or a month. Those heads remained there, rotting in the wind, for ten long years. It was a grim, silent warning to anyone crossing the bridge: do not defy the emperor. The tower suffered physically, too. Toward the end of the Thirty Years' War in 1648, the Swedish army tried to storm across this bridge to capture the Old Town. The fighting was fierce. The defenders were not just soldiers; they were local students and professors from the nearby university, barricading the gate with logs. The Swedish cannon fire completely destroyed the Gothic decorations on the side of the tower facing the river. That is why, if you walk through the arch and look back, the western face looks significantly plainer than the side you are facing now. As you pass through, you might be walking under a magical trap. The roof once hid a palindrome-a phrase that reads the same backward and forward-in Latin: Signa te, signa, temere me tangis et angis. It translates roughly to "Cross yourself, cross yourself, you touch me foolishly and suffer." It was a spell meant to ward off demons, ensuring that while armies might damage the stone, the spirit of the tower would endure.
