This large museum traces the history of the British Army, and includes interesting and thought-provoking exhibits that go well beyond a collection of military equipment (though the museum does, of course, boast a large collection of it).
The National Army Museum is the national home of the history and heritage of the Army. Through permanent galleries, special exhibitions, collections and programmes, the museum explores how soldiers have shaped our world and lives, from the British Civil Wars to the Army's role today. It was established by Royal Charter in 1960, and is a non-departmental public body sponsored by the Ministry of Defence.

Garden founded by apothecaries in the 17th century to the medicinal properties of plants. It was only opened to the public in the 1980s, when it became a charity. The heat-sink caused by its thick walls, combined with the general waste heat of London itself, keeps the garden much warmer than it would otherwise be at this latitude. Due to this, the garden contains the world's most northerly example of a grapefruit outside of a greenhouse, and the largest fruiting olive tree in the country. The collection contains thousands of different plant species.
