If you like history and meeting art on your wanderings in the city, I can recommend you take a stroll at the Wijnhaven.
This quay connects the Old Harbour (Oude Haven) with the Leuven Harbour (Leuvehaven). When you’re in the Wijnhaven Tunnel look for Rotte-Dam.
The beauty of this 26-meters-long and 2,5-meters-high corten steel wall is easy to miss during the day, so try to see it at night, when the cut out in root-shaped letters word ROTTE-DAM is illuminated by LED lighting. It just gives this ordinary place a magical atmosphere.
I find Rotte-Dam such a witty idea for this spot, as this is where the dam on the river Rotte was built 700 years ago and Rotterdam first arose. In 1870 the Rotte was filled to make space for the Overhead Railway that was replaced in 1993 by a train tunnel.
If you continue your walk you’ll pass the Willem de Kooning Art Academy and the De Willem canteen on your right hand.
