One of Amsterdam's most fascinating museums, hidden inside a 17th-century merchant house along the Oudezijds Voorburgwal canal. Following the Protestant Reformation, public Catholic worship was outlawed, leading merchant Jan Hartman to secretly build a three-storey church complete with an altar and organ across the attic floors. The site preserves authentic Dutch Golden Age domestic rooms and stands as a testament to tolerance.
