The museum is best known for its hidden church in the attic. Three centuries ago, however, visitors also came for a beer taproom (then known as a momkamer) on the ground floor.

During archaeological research in 2013, a large cesspit was excavated. The thousands of finds shed new light on this forgotten establishment. Discover this hidden (Dutch spoken) story, accompanied by a drink, in the lecture* by archaeologist Ranjith Jayasena.
