Prague Astronomical Clock

On Prague's Old Town Square stands the Town Hall Tower with its magnificent Astronomical Clock: don't miss the show at the stroke of the hour!

One of the wonders of the world stands out in the Prague sky: it is the Old Town Hall Tower, an architectural masterpiece embellished by the famous astronomical clock, one of the oldest in the world, which has become a symbol of the Czech capital.

For hundreds of years at the stroke of the hour, the Procession of the Apostles has been repeated, a fascinating mechanical ritual that has become a must-see attraction for anyone visiting Prague: 12 figures depicting the apostles parade across the top of the Tower, located in the Gothic wing of the Old Town Hall.

Perhaps it is the romantic charm of the clocks of yesteryear, perhaps it is the craftsmanship of the artisans who conceived such a complex mechanism in perfect working order, perhaps it is the extraordinary view of the city that can be enjoyed from the top of the Tower, but it is not surprising that the Clock Tower is one of the best memories tourists take home from a holiday in Prague.

Panoramic view from the Tower

Beautiful view from the Clock Tower

Thanks to a modern, barrier-free lift, you can climb to the top of the Old Town Hall Tower, where a panoramic balcony has been built. From here you can enjoy a breathtaking view of the city, with its fascinating palaces, churches and towers.

The tower is open to visitors from morning to night, so you can choose whether you prefer a daytime view, to catch a glimpse of more famous monuments, or enjoy the enchantment of a night view with the thousand lights of a fairytale Prague.

You can visit the tower during a tour of the Old Town Hall, which also includes the historical halls and basement, or visit it separately.

Astronomical Clock

The great attraction of the Old Town Hall Tower is the Astronomical Clock: photographed by hundreds of tourists every day, the clock shows time unlike any other instrument in the world. This jewel of horology is activated by an extremely complex mechanism, while some parts are purely decorative.

An early clock, the work of master clockmaker Mikuláš z Kadaň, was added to the Old Town Hall Tower in 1410. It was later perfected by Hanuš z Růže, who turned it into the marvel we admire today.

The clock was damaged on many occasions and several repairs were necessary, sometimes made possible thanks to the efforts of the local population, who saw the clock as a sign of pride. Today it is one of the best-preserved medieval clocks in the world.

The clock faces

There are two clock faces in the tower clock. The upper dial is actually an astrolabe, a medieval instrument used to determine the position of the stars: this is the oldest part of the clock. The lower dial, on the other hand, is a calendar.

Together the two dials make it possible to know the current day and its position in the week, month and year, at the same time as the position of the celestial bodies and the European, Babylonian and astronomical calendar.

The Procession of the Apostles

Four statues on either side of the clock come to life at the stroke of each hour, each with its own meaning: the figure with the mirror represents Vanity, the figure with the moneybag is Avarice, the Turk represents the barbarian invasions while the skeleton represents death.

It is the skeleton that starts the Procession of the Apostles at the stroke of each hour, ringing a bell and reversing the hourglass. The 12 apostles come out on parade and in groups of two wave to the crowd gathered in the central Old Town Square. The spectacle ends with a trumpet blast.

The wooden statues of the apostles can be admired up close, albeit through glass, during the tour of the Old Town Hall.
