Eastney Barracks, designed by
William Scamp (assistant director, Admiralty Works Department), was built as headquarters for the
Royal Marine Artillery, who moved in from
Fort Cumberland in 1867. After the amalgamation of the Royal Marine Light Infantry and Royal Marine Artillery in 1923,
Forton Barracks was closed and Eastney Barracks served as headquarters for the Portsmouth Division of the
Corps. The series of seven linked blocks facing the sea forms the second longest barracks frontage in the country (after the
Royal Artillery Barracks, Woolwich). Eastney Barracks remained the Corps Headquarters until 1995, when it was sold and converted to private housing. The
Royal Marines Museum, established there in 1958, was accommodated in the former officers' mess at Eastney Barracks from 1972 to 2017. Having deemed the building 'unsuitable' the
National Museum of the Royal Navy put the collections into storage, and in December 2020 the former officers' mess was sold to Grand Hotel Excelsior International for conversion into a "luxury hotel". ==Cadets==
