Heritage open days Leiden

Heritage Open Days has a new website

In 1987 Open Monumentendagen was introduced in Leiden. Today more than 35 monuments are open to the public; some of them are accessible this year for the first time. Feel free to compose your own walking or cycling route.

We are curious to hear about your experiences. If you have a question or a remark please let us know and write to us at openmonumentendagen@leiden.nl
