The Astronomical Clock (Pražský orloj) is built into one side of the Old Town Hall Tower (Staroměstská radnice) at the Old Town Square.
The clock dates from the 15th century. To fully appreciate its intricate construction, join the crowd in front of the tower to watch the procession of the Twelve Apostles: on the hour, every hour a trap door opens and Christ marches out ahead of his disciples, while the skeleton of death tolls the bell to a statue of a defiant Turk.
Below the Astronomical Clock are 12 medallions with the signs of the zodiac, added by Josef Manes in 1865.
Old Town Hall Tower
The Old Town Hall Tower is one of the most striking buildings in Prague. Inside is a staircase and an elevator, which visitors can climb or ride to the top to take in beautiful views over the Old Town.
The Old Town Hall Tower was constructed in 1338.
In 1364 it was knocked into a private house adjoining it, which in turn was connected to houses beside that, and the amalgamation of buildings became known as the 'Old Town Hall'.
More work was undertaken in 1470 to further integrate the houses, and it was at this time that the entire Old Town Hall building was remodelled in the Gothic style.
Tickets to climb the Old Town Hall Tower are available from the ticket office at the base of the tower. Entrance also includes entry to the historical halls of the Old Town Hall, which have been recently renovated.
Civic ceremonies, including weddings, are held in the historical halls.
Tourist Information Centre
A Prague Tourist Information Centre is located in the reception area of the Old Town Hall.
