English: Market square is dominated by the cloth hall and the 83 m (272 ft) high Belfry tower, one of the symbols of the city. The originals date from 1240. The first tower was destroyed by fire in 1280. At the time of the fire the four wings of the cloth hall already existed, as well as the two square segments of the belfry. The octagonal lantern was added between 1482 and 1486. The wooden spire that crowned the tower was again destroyed by fire in 1493 and again in 1741. After the last fire it was never rebuilt. Like in most cities the belfry tower was where important documents were preserved. The tower was also used as a watchtower. Inside hung bells, each bell having a distinct sound and function (e.g.: bells for danger, bells for important announcements, bells to indicate the time, etc.).
