Town Hall tower was built at the same time as the building itself, between 1402 and 1404. 

Soldiers of the town hall used to keep watch there. In the event of a fire or other accidents, an alarm was triggered, which can now be heard at every hour.

During the summer, visitors can enjoy the views that the tower has to offer. To reach the balcony (at 34 metres high), one must conquer 115 steps. The higher you get, the steeper and taller the steps will be.

The weather vane Old Thomas was placed at the top of the tower in 1530 and it guarded the city until 1944. The current weather vane dates back to 1996. Old Thomas I is enjoying his retirement in the basement of the Town Hall.
