The Prague Astronomical Clock or Prague Orloj

is a medieval astronomical clock, mounted on the southern wall of Old Town City Hall in the Old Town Square. The Orloj is composed of three main components: the astronomical dial, representing the position of the Sun and Moon in the sky and displaying various astronomical details; "The Walk of the Apostles", a clockwork hourly show of figures of the Apostles and other moving sculptures; and a calendar dial with medallions representing the months.
