The Royal Hospital Chelsea is a retirement home and nursing home for British soldiers who are unfit for further duty due to injury or old age, located in the Chelsea region of central London, now the Royal Borough of Kensington and Chelsea. It is a true hospital in the original sense of the word, that is a place where hospitality was provided. There are just over 300 soldiers (310, as of 10 June 2004) resident in the Royal Hospital, referred to as "in-pensioners" (or more colloquially, as Chelsea pensioners).
The grounds of the Royal Hospital have been the site of the annual Chelsea Flower Show since 1913.
