The search portal gives the public direct online access to one of the world’s largest architecture collections. The State Archive for Dutch Architecture and Urban Planning contains 1.4 million drawings; 300,000 photographs; 2,500 models and 70,000 books and magazines, which together document the history of Dutch architecture and urbanism.

Het Nieuwe Instituut preserves 700 archives and collections of Dutch architects and urban planners including P.J.H. Cuypers, H.P. Berlage, J.J.P. Oud, Gerrit Rietveld, Van den Broek & Bakema, Herman Hertzberger, Piet Blom, OMA and MVRDV. The collection’s great cultural and historical value derives not only from the artistic quality and uniqueness of the individual collections but also from the archive as a whole, which charts 130 years of developments in Dutch architecture and urbanism. Alongside presentation drawings, photographs and models, the archives contain sketches, working drawings, correspondence, posters and other documents.
