Greenwich Hospital was a permanent home for retired sailors of the Royal Navy, which operated from 1692 to 1869. Its buildings were later used by the Royal Naval College, Greenwich and the University of Greenwich, and are now known as the Old Royal Naval College. The word "hospital" was used in its original sense of a place providing hospitality for those in need of it, and did not refer to medical care, although the buildings included an infirmary which, after Greenwich Hospital closed, operated as Dreadnought Seaman's Hospital until 1986.
The foundation which operated the hospital still exists, for the benefit of former Royal Navy personnel and their dependants. It now provides sheltered housing on other sites.
The hospital was created as the Royal Hospital for Seamen at Greenwich on the instructions of Queen Mary II, who had been inspired by the sight of wounded sailors returning from the Battle of La Hogue in 1692. She ordered the King Charles wing of the palace—originally designed by architect John Webb for King Charles II in 1664—to be remodelled as a naval hospital to provide a counterpart for the Chelsea Hospital for soldiers. Sir Christopher Wren and his assistant Nicholas Hawksmoor gave their services free of charge as architects of the new Royal Hospital. Sir John Vanbrugh succeeded Wren as architect, completing the complex to Wren's original plans.
An early controversy arose when it emerged that the original plans for the hospital would have blocked the riverside view from the Queen's House. Queen Mary II therefore ordered that the buildings be split, providing an avenue leading from the river through the hospital grounds up to the Queen's House and Greenwich Hill beyond. This gave the hospital its distinctive look, with its buildings arranged in a number of quadrants. Its four main buildings (the "Courts") are bisected north-south by a Grand Square and processional route, and east-west by an internal road from the East Gate (and gate-house) to the West Gate (and gate-house) by Greenwich Market in Greenwich town centre. The Grand Square and processional route running north-south maintained access to, and a river view from, the Queen's House and Greenwich Park beyond.
