Prague Astronomical Clock
The Prague Astronomical Clock is a medieval astronomical clock located in Old Town Square in Prague. The clock was first installed in 1410, making it the oldest working astronomical clock in the world (and the third oldest in existence).
The clock can be found on the southern wall of the Old Town City Hall and has three components. The astronomical dial displays the position of the Sun and Moon in the sky along with other various astronomical details. The calendar dial features medallions that represent each month of the year. Finally, “The Walk of the Apostles” is what catches most visitors’ eyes first, as the wonderful hourly show features a parade of figures of the Apostles and other related moving sculptures heralding in the new hour.
The Prague Astronomical Clock is one of the most famous and interesting structures in the whole city – and for good reason! Come check out what everyone is talking about in Old Town Square, and literally look back across time. The clock is a marvel of science and equally as beautiful as it is complex.
