Erfgoed Leiden en Omstreken (Heritage Leiden) was formed in 2013 as the result of the merger of Regional Archives Leiden and the department of Archeology and Monuments and Sites of the City of Leiden. Heritage Leiden has a unique combination of disciplines: archivists, archaeologists, building historians, conservation specialist, museum curators, librarians and restorers. All of these disciplines work together to integrate knowledge and to tell stories of the history of the city of Leiden and it’s surrounding area, with material from their collections.

On the conviction that heritage contributes to the quality and identity of the modern world, Heritage Leiden and Region make its knowledge and collections available for use by everybody.
