Go for a walk around the historical city centre, following the trajectory of the former town ramparts on the now renovated promenade: Hoge Veser, Tichelrij, Naamsevest, Tiensevest, Kazernevest and the town park. The ramparts were erected by abbot Adelard II in the 11th century and dismantled in 1675 by king Louis XIV of France. The town park is nearly 4 ha (10 acres) large. It was laid out on the remnants of the old city walls.
