The Royal Hospital Chelsea is an old soldiers' retirement home and nursing home for some 300 veterans of the British Army. Founded as an almshouse — the ancient sense of the word "hospital" — by King Charles II in 1682, it is a 66-acre (27 ha) site located on Royal Hospital Road in Chelsea, London. It is an independent charity and relies partly upon donations to cover day-to-day running costs to provide care and accommodation for veterans.
