It's called church however one might argue it should be catherdrall for it size. The main attraction of thie church are 72 mosaic windows that are mostly massive and kept extremely well, not to mentioned they were unlocked at the begining of 2nd war and kept safe fir the duration of war. The church is 1000 years old and so worth seeing. Be sure to take guided tour which will enrich your expirence so much with knowledge of the mosaic windows. If you do decided to visit the sweet Dutch city of Gouda for the Gouda expirence then this must be also on your list as it's stone throw away from the museum.
Highly recommend!
