Of course Rotterdam has – like every other city – plenty of good and some even quite famous musea to visit. The Kunsthal and Boymans van Beuningen are probably the ones most mentioned and visited. There are however so many more places to go. Why not go to a smaller museum which is almost more like a gallery and where they have original and interactive tours every Sunday? Or go to the smallest open-air museum of the Netherlands where several bollards are drawing your attention from an otherwise very regular street.
