From the 1970s onwards the Imperial War Museum began to expand onto other sites. The first branch,
Imperial War Museum Duxford opened to the public on a regular basis in June 1976. became a branch of the museum in 1978. The
Churchill War Rooms opened in 1984, and
Imperial War Museum North in 2002.
Imperial War Museum London Architecture and layout in 1828 The museum has occupied the former Bethlem Royal Hospital on
Lambeth Road since 1936. The hospital building was designed by the hospital surveyor, James Lewis, from plans submitted by
John Gandy and other architects, and construction completed in October 1814. The hospital consisted of a range of buildings 580 feet long with a basement and three storeys, parallel to
Lambeth Road, with a central entrance under a
portico. The building remained substantially unchanged until vacated by the hospital in 1930. After the
freehold was purchased by
Lord Rothermere, the wings were demolished to leave the original central portion (with the dome now appearing disproportionately tall) and Smirke's later wings. When the museum moved into the building in 1936 the ground floor of the central portion was occupied by the principal art gallery, with the east wing housing the Naval gallery and the west wing the Army gallery. The Air Force gallery was housed in the former theatre. The first floor comprised further art galleries (including rooms dedicated to
Sir William Orpen and
Sir John Lavery), a gallery on
women's war work, and exhibits relating to transport and signals. The first floor also housed the museum's photograph collection. The second floor housed the museum's library in its west wing, and in the east wing the
map collection and stored pictures and drawings. This division of exhibits by service, and by civil or military activity, persisted until a wide-ranging redisplay of the galleries from the 1960s onwards. In September 1972 the building received Grade II
listed building status. The original hospital building is now largely occupied by corporate offices. The 1966 extension houses the library, art store, and document archives while the 1980s redevelopments created exhibition space over five floors. The first stage created 8,000 m2 of gallery space of which 4,600 m2 was new, and the second provided a further 1,600 m2. and provided 5,860m2 of gallery space and educational facilities over six floors. Before the 2013–14 redevelopment, the basement was occupied by permanent galleries on the First and Second World Wars, and of conflicts after 1945. The ground floor comprised the atrium, cinema, temporary exhibition spaces, and visitor facilities. The first floor included the atrium mezzanine, education facilities, and a permanent gallery,
Secret War, exploring
special forces,
espionage and
covert operations. The second floor included the atrium viewing balcony, two art galleries, a temporary exhibition area and the permanent
Crimes against Humanity exhibition. The third floor housed the permanent
Holocaust Exhibition, and the fourth floor, a
vaulted roof space, accommodated the Lord Ashcroft Gallery. Opened in November 2010 the gallery exhibits the museum's
Victoria Cross (VC) and
George Cross collection, alongside the private VC collection amassed by
Michael Ashcroft, 241 medals in total. The Lord Ashcroft Collection was on loan for ten years, was extended for a further five years because of COVID, and the termination of the loan was first confirmed in July 2024, resulting in the closure on 1 June 2025. In August 2019, the museum announced plans to spend over £30 million on a new set of galleries over two floors at its London site covering the Holocaust and its importance in World War II. The galleries opened in October 2021 to replace the existing permanent exhibition.
All Saints Annexe In 1989 the museum acquired the All Saints Annexe, a former hospital building in Austral Street off
West Square. The 1867 building, which backs onto
Geraldine Mary Harmsworth Park, was originally an orphanage opened by local
philanthropist Charlotte Sharman, then later used as a hospital. It housed the museum's photographic, film and sound archives, and offices.
Imperial War Museum Duxford Imperial War Museum Duxford, near the village of
Duxford in
Cambridgeshire, is Britain's largest
aviation museum. Duxford houses the museum's large exhibits, including nearly 200
aircraft, military vehicles, artillery and minor naval vessels in seven main exhibitions buildings. The site also provides storage space for the museum's collections of film, photographs, documents, books and artefacts. The site accommodates a number of
British Army regimental museums, including those of the
Parachute Regiment and the
Royal Anglian Regiment. Based on the historic
Duxford Aerodrome, the site was originally operated by the
Royal Air Force (RAF) during the
First World War. During the
Second World War Duxford played a prominent role during the
Battle of Britain and was later used by
United States Army Air Forces fighter units in support of the
daylight bombing of Germany. Duxford remained an active RAF airfield until 1961. Many of Duxford's original buildings, such as
hangars used during the Battle of Britain, are still in use. A number of these buildings are of architectural or historic significance and over thirty have
listed building status. The site also features a number of purpose-built exhibition buildings, such as the
Stirling Prize-winning American Air Museum, designed by
Sir Norman Foster. The site remains an active airfield and is used by a number of civilian flying companies, and hosts regular
air shows. The site is operated in partnership with
Cambridgeshire County Council and the Duxford Aviation Society, a charity formed in 1975 to preserve
civil aircraft and promote appreciation of British civil aviation history.
HMS Belfast (1938) HMS
Belfast, a
Town class cruiser, was launched in 1938 and served throughout the
Second World War, participating in the December 1943
Battle of North Cape and firing some of the first shots of
Operation Overlord, the Allied invasion of Normandy in June 1944. She saw further combat in the
Korean War. Expected to be disposed of as scrap after she was decommissioned in 1963, in 1967 efforts were initiated to preserve
Belfast as a museum ship. A joint committee of the Imperial War Museum, the
National Maritime Museum and the
Ministry of Defence was established, and reported in June 1968 that preservation was practical. In 1971 the government decided against preservation, prompting the formation of the private HMS
Belfast Trust to campaign for her to be saved for the nation. The Trust was successful in its efforts, and the government transferred the ship to the Trust in July 1971. Brought to London, she was moored on the
River Thames near
Tower Bridge in the
Pool of London. Opened to the public in October 1971
Belfast became a branch of the Imperial War Museum on 1 March 1978, being acknowledged by the then
Secretary of State for Education and Science,
Shirley Williams, as "a unique demonstration of an important phase of our history and technology". In service for 24 years HMS
Belfast was in Frankland's opinion, capable of representing "a whole generation of [historical evidence]". In 2017, the name of the exhibit was changed to "HMS
Belfast 1938" to reflect that one of the Royal Navy's new
Type 26 frigates had been given the name HMS
Belfast.
Churchill War Rooms The Cabinet War Rooms is an underground complex that served as a British government command centre throughout the Second World War. Located beneath the
Treasury building in the
Whitehall area of
Westminster, the facilities became operational in 1939 and were in constant use until their abandonment in August 1945 after the
surrender of Japan. Their historical value was recognised early on, and the public were able to visit by appointment. However, the practicalities of allowing public access to a site beneath a working government office meant that only 4,500 of 30–40,000 annual applicants to visit the War Rooms could be admitted. The museum agreed to take over the administration of the site in 1982, In 2005 the War Rooms were rebranded as the Churchill Museum and Cabinet War Rooms, with 850 m2 of the site redeveloped as a biographical museum exploring Churchill's life. The development of the Churchill Museum cost a further £6 million. The centrepiece is a 15 m interactive table which enables visitors to access digitised material, particularly from the
Churchill Archives Centre, via an "electronic filing cabinet". The museum was renamed the Churchill War Rooms in 2010.
Imperial War Museum North in
Manchester The Imperial War Museum North was opened in
Trafford,
Greater Manchester, in 2002. It was the first branch of the museum outside southeast England, and the first to be purpose-built as a museum. Designed by architect
Daniel Libeskind, with Manchester-based architects Leach Rhodes Walker providing implementation services, The Imperial War Museum North was Libeskind's first building in Britain. Libeskind's building, overlooking the
Manchester Ship Canal at
Salford Quays, was based on the concept of a globe shattered by conflict into shards and reassembled. These shards, representing earth, air and water, give the building its shape. Originally budgeted at £40 million, the museum was completed for £28.5 million after anticipated funding was not forthcoming. The museum was funded by local, national and European development agencies, by private donations and by
Peel Holdings, a local transport and property company which contributed £12.5 million. tank on display The museum's first floor main gallery space houses the permanent exhibitions. These consist of a chronological display which runs around the gallery's 200m perimeter and six thematic displays in "silos" within the space. The walls of the gallery space are used as screens for the projection of an hourly audiovisual presentation, the Big Picture. The main gallery, described as cavernous and dramatic, includes objects such as a Russian
T-34 tank, a
United States Marine Corps AV-8A Harrier jet, and a British
13-pounder field gun which fired the
British Army's first shot of the First World War. The museum also hosts a programme of temporary exhibitions, mounted in a separate gallery.
