Prague astronomical clock

The Prague Astronomical Clock is a big clock that can tell time like the clock in your house, but it can also show you some other special things.

The clock has two main parts - the top part and the bottom part. On the top part, there are different circles that show you where the sun and the moon are, and what time of day it is. There are also little figurines that move around and show you the 12 apostles, which were special helpers of Jesus a long, long time ago.

The bottom part of the clock has little doors that open up at specific times. There is a little figure of a skeleton that rings a bell and shows you that another hour has passed. There are also little figures of people that move around and do different things, like a man that nods his head to show you that it is time for a new day.

The Prague Astronomical Clock is very important and many people come to see it because it has been around for more than 600 years! It is a special way for people to tell time and remember history at the same time.
