European Heritage Days in The Netherlands

During the 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 organise on-site activities like exhibitions, music and guided tours. Each year around 80 to 85 percent of Dutch municipalities participate in the Open Monumentendag, organised by local committees. In recent years around 900,000 visitors have participated annually, making the Open Monumentendag one of the Netherlands' premier cultural events.
