I had only half an hour before the Boijmans Museum closed:  not nearly enough time to see a major European collection, austerely, but beautifully displayed in spookily empty galleries.   I liked The Last Supper by Jörg Ratgeb:-

Just time to see and appreciate the astonishing collection of Rubens sketches before closing time:-

Afterwards, I was able to admire its exterior, a nice piece of 1935 civic modernism by the city architect, A. van der Steur:-
