Oudezids Voorburgwal 40

Ons’ Lieve Heer op Solder was an illegal church hidden in the attic of a house in Amsterdam during the Reformation when Catholics were forbidden to hold public ceremonies. Today it is a museum which is located in the red light district of the city. It is a nice place to visit if you are interested in this part of Dutch history and you can also see temporary art exhibitions or take a guided tour of the church and house.
