Our Lord in the Attic Museum

The Museum Ons' Lieve Heer op Solder hides inside a narrow 17th-century canal house in the heart of Amsterdam's Red Light District. After the Reformation, public Catholic worship was banned in the Netherlands, so in 1661 the merchant Jan Hartman installed a full clandestine church, a so-called schuilkerk, in the upper floors of his home. The hidden church, with its gallery, organ, and marble altar, is one of the few that survives in Europe and carries the European Heritage Label. Visitors climb steep stairs through a Baroque sacristy and the family's original sitting room. The church still hosts weddings, concerts, and lectures on religious freedom.
