During Open Monumentendag – every second weekend of September – thousands of historical buildings and sites (about 4.000) are open to the public free of charge. Besides opening their doors, many locations also organize on-site activities like exhibitions, musical performances and guided tours. Each year around 80 to 85 percent of Dutch municipalities participate in the Open Monumentendag, organized by local committees.
