The Belfry of Thuin is the historic belfry of the Walloon city of Thuin, once one of the good cities of the Prince-Bishopric of Liège. This civic tower, dating from the 17th and 18th centuries, was once the tower of the (former) collegiate church.
The belfry has been a UNESCO World Heritage Site since 1999, a list that has since grown to 56 belfries in Belgium and France.
The belfry towers over the other buildings on the hill on which Thuin was built. It has stood here since 1639 and, together with the other bell towers of this type in Flanders and Wallonia, is a UNESCO World Heritage Site.
