Royal Museums Greenwich

Royal Museums Greenwich is the group that brings together four historic visitor sites in Greenwich: the Royal Observatory, the Cutty Sark, the National Maritime Museum and the Queen's House. It also looks after the Prince Philip Maritime Collections Centre and the Caird Library and Archive, which its own pages describe as holding the world's largest maritime library and archive collection. Its stated purpose is to enrich public understanding of the sea, the exploration of space and Britain's role in world history. For astronomy and spaceflight readers the Royal Observatory is the link, since the organisation runs its space and astronomy programme of exhibitions, stories and school sessions, including the annual astronomy photography competition it hosts. It operates collections, conservation, research and learning programmes alongside its public galleries.
