One of our favourite sources for architectural photography, the Royal Institute of British Architect's Photographs Collection, is celebrating a landmark moment. Its online database,, has this week reached a total of 50,000 images, making it an invaluable virtual resource for research and inspiration.
Well known for its documentations of architecture and the built environment, both in the UK and abroad, the RIBA archive also holds a number of rare drawings, engravings and written material. The full archive holds over 1.5 million images, more of which will soon be available on, where prints of them are also available to buy.
