Who Built the Astronomical Clock in Prague?

By Anna Duncan

Have you ever visited Prague and seen the magnificent Astronomical Clock? It’s a stunning piece of medieval engineering that has fascinated tourists for centuries.

But have you ever wondered who built it? Let’s take a closer look at the history of this famous clock.

The Origins of the Astronomical Clock

The Astronomical Clock, or Orloj as it is locally known, was first installed in Prague in 1410. It was designed by the renowned clockmaker Mikulas of Kadan and constructed by Jan Sindel, a skilled astronomer and mathematician. The clock was initially installed on the southern wall of Old Town City Hall, where it still remains today.

The Features of the Clock

The Astronomical Clock is not just a timepiece; it also displays astronomical information and has several other features. The clock face has two main circles – an outer ring with Roman numerals that indicate the hours and an inner ring with Arabic numerals that display the minutes. There are also four smaller dials that show the phases of the moon, equinoxes, zodiac signs, and the sun’s position in relation to different constellations.

One of the most fascinating features of the clock is its hourly performance. At every hour, a small trapdoor opens above the clock face, and wooden figures representing different vices (vanity, greed, death, and lust) move around while a skeleton rings a bell. This performance attracts crowds every hour.

The Restoration Process

Over its 600-year history, the Astronomical Clock has undergone several restorations to keep it functioning correctly. The first significant restoration took place in 1560 when Master Hanus repaired some elements damaged by fire. In 1787 Josef Manes restored some parts as well as adding new ones to improve accuracy.

The most recent restoration took place in 2005, when the clock underwent a complete overhaul. This restoration was the most extensive and expensive in the clock’s history, costing over 20 million Czech crowns. The restoration team replaced old parts with modern ones to ensure better accuracy and durability.

The Legacy of the Clockmakers

The Astronomical Clock has endured for over six centuries and remains one of Prague’s most popular tourist attractions. It is a testament to the skill and ingenuity of its creators, Mikulas of Kadan, and Jan Sindel.

In conclusion, the Astronomical Clock is not just a clock; it’s a piece of history that represents the achievements of medieval engineering. Its continued operation after all these years is a tribute to its makers’ expertise and dedication. Whenever you are in Prague, make sure to visit the Astronomical Clock to witness its hourly performance and experience its historical significance.
