Ons' Lieve Heer op Solder Museum


Ons' Lieve Heer op Solder is a clandestine church in the attic of a canal house in the Wallen district of Amsterdam. The attic church was founded by Jan Hartman in 1661 in response to the Reformation, which forbade Amsterdam Catholics from practicing their faith in public. Today, 70,000 visitors come to see the Ons’ Lieve Heer op Solder Museum each year to admire the church in all its glory and to learn more about the history of Catholics in Amsterdam.

Church of Amsterdam

There are many churches in Amsterdam, but the story of Ons’ Lieve Heer op Solder is unique. At the time Jan Hartman had his house converted to a clandestine church, he could never have suspected that it would first serve as a parish church for Amsterdam Catholics for 200 years and then go on to become one of the city’s first museums.

If you visit the church in the Wallen district of Amsterdam today, you will first be guided through the entire canal house. Via various works of art and exhibits, you will learn all about the 17th century house, Jan Hartman and Amsterdam’s history with various religions over the years. Although the Protestant government quickly caught wind of this clandestine Catholic church, it implemented a policy of tolerance which made room for all religious denominations which deviated from Protestantism.

Visit the clandestine church

In 1887, the St. Nicholas church took over the function of parish church from Ons' Lieve Heer op Solder. Within a year, the former clandestine church of Amsterdam was assigned a new function, that of a museum, and the doors were opened to the public. After the Rijksmuseum, it is the oldest museum in the city. During your visit to the Ons' Lieve Heer op Solder, be sure to pay special attention to the centuries-old elements and art objects, and remember that Amsterdam Catholics worshipped here for two centuries.
