This weekend is Open Monumentendag, or Open Monument Day, in the Netherlands. Across the country, over 6,000 monuments open their doors to the general public for free on the second weekend of September, with 2026 being the 40th event. 

Nearly 300 monuments and historical sites around Limburg will be open, including several in Sittard, Heerlen, Maastricht, and Valkenburg. Some sites are not open regularly, and others are normally paid entry. 

Some places will have activities for children, and there is a photography competition for anyone handy with a camera. The monuments range from country castles, wonderful windmills, fearsome forts, and more.
