Museum Ons' Lieve Heer op Solder

Travel back to a time when it was illegal for Catholics to hold open masses in Amsterdam. One Catholic man had a plan. During the Reformation period, Jan Hartman created a hidden church in the top floors of his canal house, now Ons' Lieve Heer Op Solder or Our Lord in the Attic in English. Unless one knew otherwise, from the outside the naked eye could not detect that there was a church set-up inside. At the time, authorities did know the church existed, but they simply ignored it. It's definitely a place you should see for yourself. Plus, it allows you to see a historic Amsterdam canal house. The audio tour, available in seven languages, is included in the entrance fee. From October to April, stop by on the first Sunday of the month at 11:00 to experience an Attic celebration. Please note, no photography or recordings are allowed.
