Sint-Germanuskerk Northeast Belgium

Sitting on Tienen's central rise, Sint-Germanuskerk's remarkable early-13th-century belfry is a towering Romanesque structure topped by 16th-century octagonal topknot. It's one of 23 Flemish belfries that are Unesco World Heritage monuments. Getting inside requires a call to the caretaker but on Wednesdays in July and August you can listen from outside to a carillon concert that rings out across town.
