In 2004, the V&A alongside Royal Institute of British Architects opened the first permanent gallery in the UK covering the history of architecture with displays using models, photographs, elements from buildings and original drawings. With the opening of the new gallery, the RIBA Drawings and Archives Collection has been transferred to the museum, joining the already extensive collection held by the V&A. With over 600,000 drawings, over 750,000 papers and paraphernalia, and over 700,000 photographs from around the world, together they form the world's most comprehensive architectural resource.
