The architect of the City Hall, Matthew Layens of Leuven, was called to draw up plans. It was to be a building in Gothic style, but it seems that the plan (which was not found) was not completed, including the abandonment of the second floor, which was still intended for construction. The Renaissance campanile was added in the 18th century. It contains a bell dating from 1390, the Bancloque, and carries a clock dial overlooking the Grand Place and a light clock. The 19th century saw various modifications of the façade, the removal of stone mullions to the floor and various stone ornaments.
