The tower that houses the clock became an addition to the house that makes up the Town Hall in 1364. This tower was of importance because of how towers symbolized power and security for Czech society. Mikuláš of Kadaň, under the direction of the King, created the clock in 1410, with a calendar plate and the Death figure added in 1490 by Jan Růže.

In May 1945, the Nazis destroyed the Town Hall, resulting in damage to the clock mechanism and the wooden figures. The clock was operating again in 1948 with new figures.

In 1976, replicas replaced the original statues and sculptures. The originals are on display in the Prague City Museum.
