When was the Prague Astronomical Clock built?

The original mechanism was installed on 9 October 1410. In 1490, the clockmaker Jan Růže expanded the ensemble by adding the lower calendar. It is the oldest astronomical clock in the world in continuous operation.

How many times a day does the show run?

Every hour on the hour, from 9:00 to 21:00. That is 13 shows daily, each lasting less than a minute.

What does the golden cockerel mean?

The golden cockerel crowns the show, crowing and spreading its wings at the end of the apostles' procession. The cockerel is a symbol of dawn, vigilance and the passage of time. In the medieval Christian tradition, the cock's crow also marks the end of night and the start of day, separating the time of sleep from the time of work.

Is it free to watch the Astronomical Clock show?

Yes. The hourly show is completely free; you simply need to be in the Old Town Square. Going up the Town Hall tower to see the mechanism from inside and the panoramic views has a paid admission.

What is the best position to watch the show?

From the square, facing the tower directly. The more centred you are in relation to the clock, the better. During peak summer hours, the square can be completely full; arrive 10 minutes early to secure a spot.

How much time should you dedicate to the Astronomical Clock?

To watch the show and examine the mechanism from the square: 20-30 minutes. To go up the tower as well: add 45 additional minutes. The free tour includes the stop with full context in approximately 15 minutes.
