The building that houses Ons' Lieve Heer op Solder in Amsterdam was originally constructed in 1630. Between 1661 and 1663, the top three floors were ingeniously transformed into a clandestine house church, providing a space for religious dissenters to worship privately. This historic site then reopened to the public as a museum in 1888, becoming the second-oldest museum in Amsterdam. Formerly known as Museum Amstelkring, it has since been recognized as Rijksmonument 6107 and was awarded the European Heritage Label in 2024.
