Open Monumentendag
About
Open Monumentendag ("day of the open monuments"), on this national event, many monumental buildings can be visited for free, which are otherwise closed to the public. This includes climbing to the top of "Molen De Roos", the windmill on Phoenixstraat 112, and visiting the former city prison and torturing room (backside of the City Hall), where the alleged murderer of William of Orange was tortured in 1584. It usually takes place on a Saturday. Inform at the tourism office when the next open monumentendag is held.
