The belfry of Namur, also called the Tour Saint-Jacques (“Saint Jacob’s Tower”), is an historical building of the city of Namur, Belgium. The tower, constructed in 1388 as part of the city wall, became a belfry in 1746. It is one of the 56 belfries of Belgium and France classified in the world patrimony of the UNESCO.

At the beginning of the 18th century, the city wall was demolished but the Tour Saint-Jacques was preserved and restored, and its clock was covered by an octagonal structure. This entire part was lifted upon a clock bulb. The Tour Saint-Jacques became Namur’s city belfry in 1746. Thus the belfry of Namur is a military defence tower reallocated to civil use.
