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.
