The Old Town Hall is one of the most significant monuments in the Czech Republic. It was established in 1338 as the administrative seat for Prague's Old Town. Now, it is mainly used for the ceremonial purposes of the capital city, Prague. The historical town hall consists of a set of five medieval houses, the corner of which is adorned with a historical astronomical clock, a gothic oriel window and a massive rectangular tower. The lookout gallery on the town hall tower offers the most beautiful view of Prague. A tour of the historical halls in the Old Town Hall is a unique experience. The expensively decorated rooms date from various periods and are examples of the remarkable development of the town hall complex. The guided tours in various languages are organised in half-hourly intervals.
