Old Town Hall, Prague, Czech Republic Royalty-Free Stock Photo

The burghers of the Old Town extended their original Town Hall towards the west by buying the adjoining house and they started the construction of a stone tower on a square plan. The tower, which was the highest in the city in the Middle Ages, was completed in 1364 and the following centuries hardly left any traces on the structure. The Town Hall is one very unusual historical object, because it is made out of many different smaller houses. The expansion continued in 1458 when so called `Mikes` house` was added to the west side. The Council Chamber in the east wing was vaulted with the net vault, which was supported with 2 pillars, at the end of the 15th century.
