Why locals love it
FOAM is Amsterdam's most favorite photography museum. That has multiple reasons: It is in the middle of the centre, so owners of a Museumkaart can hop by any time and that it is not too big (but definitely not too small). That makes it perfect for a visit. You can be amused for hours, but if you want you can see all the art within one hour.
Why you should visit it
If you are into photography, a visit to FOAM might turn out to be one of the best memories of your visit to Amsterdam. The expositions very divers and changed multiple times per year. Check the website to see what is going on during your stay.
