Town hall in Olomouc, Gothic town hall in Upper Square, Czech Republic

The town hall of Olomouc is a four-wing, two-storey Gothic building from 1378 on Horní náměstí, with an inner courtyard and a 75-metre tower topped by a Renaissance arcade gallery. Its astronomical clock, first mentioned in 1519, was rebuilt in socialist-realist style by Karel Svolinský between 1947 and 1955.

Jošt Lucemburský authorised the town hall in 1378 and the first stone was laid that year; a provisional wooden structure stood in 1410–1411, and the stone building was finished in 1443. A second floor with a Gothic hall and clock room was added in 1474, and the tower reached its present 75 m with a Renaissance arcade gallery in 1601–1607. The astronomical clock was destroyed at the end of World War II and rebuilt by Karel Svolinský in 1947–1955.

The astronomical clock on the facade shows scenes of the life and work of the people of the Haná region, created by Karel Svolinský in 1955. The tower's gallery displays stone coats of arms of the lands of Austria-Hungary, with the city's own coat of arms beneath the cornice.

The tower rises to 75 m and carries a Renaissance arcaded gallery at its top; the building's four wings enclose an inner courtyard. Two clock bells, cast in 1501 and 1603, are displayed on a metal frame in the courtyard after restoration. Exhibitions on the city, the astronomical clock and the town hall are housed inside.

Inside the building there is a chapel with vaulted ceilings that preserves medieval details. Beneath the square lie old dungeons that can be explored on special tours, revealing how the city once punished people.
