Established 1338 as the seat of the Old Town authorities. The oldest gothic part of the complex which includes a tower and an oriel chapel is richly decorated with coats of arms. It was built in the latter half of the 14th century. In the top part of the astronomical clock (early 15th century) the 12 apostles appear every hour between 9 a.m. and 9 p.m. The bottom part was supplemented with a round calendarium including the signs of the zodiac painted by Josef Mánes (1865). The eastern pseudo-gothic wing of the Town Hall was destroyed on May 8, 1945, and has not been rebuilt yet.
