You could be mistaken in thinking this is a church tower. But it's not. It is in fact a (former) watertower. We call it the Poldertoren. It's octagonal and it's the result of a contest for architects. This design won and was subsequently built. Right at the top there is a 'carillion' or Glockenspiel, which is not solely for churches in the Netherlands.
Nowadays it houses the Information office and a restaurant. And you climb to the top to see the view (which I have yet to do).
