Old Town's ancient town hall was established in 1338 after the agreement of King John of Luxemburg to set up a town council. Several old houses had to be knocked together over the centuries as the Old Town Hall expanded. A Gothic chapel and a neo-Gothic north wing were destroyed by the Nazis in spring 1945. The chapel has been reconstructed. The most popular part of the tower is the Town Hall Clock (Orloj). Originally instaled in 1410, the clock was rebuilt by the Master Hanuš in 1490. It consists of three parts – the procession of Apostles, the astronomical clock and the calendar. The main attraction is the hourly procession of the 12 Apostles. The height of the tower is 69,5 m and it offers a great view of the city.
