The Old Royal Naval College is the architectural centrepiece of Maritime Greenwich, a World Heritage Site in Greenwich, London, described by the United Nations Educational, Scientific and Cultural Organization as the "finest and most dramatically sited architectural and landscape ensemble in the British Isles". The buildings were originally constructed to serve as the Royal Hospital for Seamen at Greenwich, now generally known as Greenwich Hospital, which was chartered by King William III and Queen Mary II on 25 October 1694, designed by Christopher Wren, and built between 1696 and 1712. The hospital closed in 1869. Between 1873 and 1998 it housed the Royal Naval College, Greenwich.
