Broel Towers and Broel Bridge

The Broel Towers (Dutch: Broeltorens) are a landmark in the Belgian city of Kortrijk (Courtrai). The towers are known as one of the most important symbols of the city. Although they look identical, the towers were not built at the same time. The Southern tower, also known as the Speyetoren, was built in 1385 to control the traffic on the river Lys. The Northern tower, known as the Ingelborchtoren was built in 1415 and was used as an armory.
