Prague Astronomical Clock: How It Works and What to See

Crowds gather in Old Town Square before every hour, phones raised, and the show is over in about a minute. Many people walk away unsure what they just saw. The Prague Astronomical Clock is more than a procession of figures. Its dials track the Sun, the Moon, and four ways of counting hours, and its statues carry medieval warnings about vanity, greed and death. This guide explains how it works, what each part means and how to fit it into a Prague trip.

Key Takeaways

What Happens During the Prague Astronomical Clock's Hourly Show?

1. Death, the skeleton on the right, pulls a bell cord and the bell tolls.
2. Two small windows above the dial open.
3. The Twelve Apostles pass the windows one by one.
4. Other figures beside the dial move too. The Turk shakes his head, and the miser shakes his purse.
5. The golden rooster crows, the windows close, and the clock strikes the hour.

Tribe Travel Tip: The sequence lasts about a minute. Therefore, arriving early helps you find a clear view.

How to Read the Prague Astronomical Clock

This astronomical clock has two main dials. The upper one tracks the sky and several kinds of time. The lower one is a calendar.

1. Understanding the Upper Astronomical Dial

• Sun: A golden disc on a hand. Its position shows the time and where the Sun sits in the sky.
• Moon: A ball, half silver and half dark, that rotates to show the Moon's phase.
• Zodiac ring: An off-centre ring that turns once per sidereal day, about 23 hours 56 minutes. The Sun's place against it shows its zodiac position.
• Coloured areas and curved lines: Blue is the daytime sky, red is dawn and dusk, and black is night. The curved gold lines mark unequal hours.

2. What Are the Four Time Systems?

Several systems appear because medieval daily life followed sunset and daylight, while astronomers needed star time.

3. What Does the Lower Calendar Dial Show?

• Calendar Dial: Shows the months and zodiac signs.
• Date Pointer: Points to the current date and moves at midnight.
• Artwork: Painted by Josef Mánes between 1865 and 1866.
• Original Dial: The original artwork is kept at the Prague City Museum, and a copy is displayed on the clock tower.

What Do the Figures Around the Clock Represent?

• Death: The skeleton with an hourglass, a reminder that time runs out.
• Vanity: A figure admiring himself in a mirror.
• Greed or Miserliness: A figure with a purse. Older accounts attach an antisemitic stereotype to it, and most current guides simply say greed.
• Lust: The Turk, who holds a lute. Guides read him as earthly pleasure, though some see a foreign threat.
• Twelve Apostles: The only figures that parade, appearing at the windows each hour.
• Other figures: The Philosopher, Astronomer, Chronicler, and an angel usually named Archangel Michael. They are fixed statues, and sources disagree on their meaning.

What Is the History of the Prague Astronomical Clock?

• 1410: Clockmaker Mikuláš of Kadaň built the clock's mechanism, and astronomer Jan Šindel is credited with its astronomical design.
• Around 1490: The calendar dial and Gothic sculptures were added, with work linked to clockmaker Jan Růže, known as Hanuš.
• The Hanuš Legend: A popular story claims that Master Hanuš was blinded to stop him from building another clock. However, there is no evidence to support this, and he worked on the clock about 80 years after its creation.
• 1945: A fire during the Prague Uprising damaged the clock and destroyed its wooden sculptures.
• 1948: The clock resumed working with new statues of the Twelve Apostles carved by Vojtěch Sucharda.
• 2018: Major reconstruction work took place, and the clock resumed operation on 28 September.
• Its Age: It is often called the world's oldest working astronomical clock, though Radio Prague describes it as the third oldest operating clock.
