Stunning, full size church built in an attic built during the Dutch Reformation when Catholicism was banned. Preserved, beautiful, and full of original items for worship. It was an amazing afternoon. The private tour guide was extremely well versed and interesting.

A fascinating museum unlike anything I have seen elsewhere. I must specially commend the provision for disabled visitors. Like many old buildings, it has proved difficult to provide access. Rather than give up, they provide a “covisit” facility; whereby a companion explores the museum guided by the disabled visitor, maintaining full audio/visual contact. I have never encountered this before. It was an innovative response to an impossible situation and allowed us to explore together. Frankly it was tremendous fun. I wish others were as innovative.

Original 1600s house with its little changed interiors. Entry via next door house with modern facilities. Basement floor links to the old house which has six floors. The top 3 floors contain the hidden Catholic church, the bottom 3 floors used by the family. We spent longer than the 1 hour visit we anticipated. Free audio tour, some original narrow wooden staircases to negotiate.

This is a little diamond that might be missed by visitors hurrying through the city. The house is really lovely and delivers a real idea of life for a well off family living by the canals. The church itself is breathtaking despite its small size. Thanks to the brilliant staff. Included on the IamAmsterdam card, it should not be missed.

.. that Catholics had to hide (= not display) their churches at one time. Lovely church but doesn't take long to go around and if you don't have e.g. an IAmsterdam card at 16 Euros is quite expensive.

Really interesting and well presented museum. Very friendly staff on the front desk. The entrance is in an adjacent property and after watching a short film you walk through to the house below street level. The house itself is intersting to see although quite empty but the church is stunning. Really good audio guide once you've worked out how to use it (there were pictures to show you but we couldn't quite understand it).

Recommended by a work colleague and really glad we took the recommendation. Interesting to learn some history and see how the Dutch lived in times past. Excellently preserved. Very friendly and helpful staff.

First, obviously, be sure to look for the signs that say Museum Ons'Lieve Heer Op Solder and not expect to see it in English “Our Lord in the Attic” otherwise you will walk right past it. The front entrance appears modern but you quickly enter and “step back in time”. It is very interesting to see the inside of the house and then the church and one realizes the depth of faith to continue to practice their religion. Plan to spend an hour or so…

Although Amsterdam has several world class museums, this was my favorite museum because it captures such a unique period of history. It is the only remaining hidden Catholic Church of the ~21 that existed when Catholics were prohibited from worshipping openly. I was struck by the ingenuity of the architects who built the church across the attics of three houses. When inside the church don’t miss the video showing the hidden pulpit.

This was a fascinating and well presented museum. A simple audio device that you could activate at various points along the tour told you all the details and I noticed there was a separate children's one. It is spread over several floors up and down lots of narrow stairs but lots of people of all ages were managing fine. Really interesting place to visit.
