The History of the Olomouc Astronomical Clock

The original clock dates back to the 15th century. It was a masterpiece of Gothic engineering. Over the centuries, it was updated many times. By the early 20th century, it had a beautiful Baroque appearance. Sadly, the clock was heavily damaged in 1945.

German troops retreating from the city fired upon the Town Hall. The clock was almost entirely destroyed. After the war, the city had to decide how to fix it. The new communist government wanted a modern look. They chose to replace religious figures with socialist icons.

The task went to artist Karel Svolinský. He worked on the design from 1947 to 1955. He used glass mosaics to create a vibrant display. You can find more hidden gems in Olomouc that date back to this era. Today, it stands as a rare example of socialist art on a public monument.

The clock is part of a UNESCO World Heritage site. It is located in the Upper Square, or Horní náměstí. For more general info, check the Olomouc Tourism Portal. It is a must-see for anyone interested in Cold War history.
