Starom?stské Nám?stí The 12th-century Old Town Square is another focal point for tourists in Prague. In summer, tables spill out from the restaurants, while in December the square hosts the city’s largest Christmas Market. All of the palaces, churches and houses around the square are of major historical interest, such as the gothic Staromestska Radnice (Old Town Hall). Its Astronomical Clock has become a must for visitors, although the spectacle doesn’t quite live up to its billing. It strikes hourly from 0900-2100, when the 15th-century upper portion reveals the Apostles at two windows. Expect large crowds in summer. Just off the square, to the east, is the superb gothic Chram Matky Boži P?ed Tynem (Tyn Church), where the tomb of the astronomer Tycho Brahe is found.
