Heritage open days Leiden

Info /

Unfortunately for our English-speaking guests we will communicate mainly in Dutch. Hopefully our flyer and English site will be of help.

During the weekend of 10-11 September 2022. 34 monumental buildings in Leiden open their doors to the public. Many monuments host small exhibitions, as well as performances by choirs from Leiden. This year's theme is  'Sustainable heritage'. From centuries-old insulation materials to hypermodern technologies: discover how sustainable Leiden's monuments are.

Follow us on Twitter (@OMDLeiden) or Facebook. Sorry to inform you that we communicate mainly in Dutch. You may be surprised to learn that Open Monumentendagen Leiden is solely organised by volunteers. With an English flyer and limited English information on our website we hope to serve an international public. Would you like to be involved, please let us know

Heritage Days Leiden

This year's theme Duurzaam duurt het langst derives from the European theme Sustainable Heritage. The VriendenLoterij Open Monumentendag is a yearly event organised by the Open Monumentendagen Leiden and the national bureau Open Monumentendag in cooperation with VriendenLoterij. In organising this event we aim to increase awareness for monuments in general and in particular make Dutch cultural heritage accessible and keep for a wide audience. Our foundation is locally sponsored and we organise this event each year in the 2nd weekend in September. This year on 10 and 11 September. In Leiden there are open 34 monuments on these dates. Enjoy!
