Переведите на казахский язык.Только правильно. Без переводчик)
The Tate is an institution that houses the United Kingdom`s national collection of British Art, and International Modern and Contemporary Art. It is a network of four art museums: Tate Britain, London (previously known as the Tate Gallery), Tate Liverpool, Tate St Ives, Cornwall and Tate Modern, London, with a website, Tate Online.
The Tate Britain was founded in 1897, as the National Gallery of British Art. When its role was changed to include the national collection of Modern Art as well as the national collection of British art, in 1932, it was renamed the Tate Gallery after sugar magnate Henry Tate of Tate and Lyle. who had laid the foundations for the collection.
The original Tate art gallery was called the National Gallery of British Art, situated on Millbank, Pimlico, London at the site of the former Millbank Prison.The idea of a National Gallery of British Art was first proposed in the 1820s by Sir John Leicester, Baron de Tabley. It look a step nearer when Robert Vernon gave his collection to the National Gallery in 1847. A decade later John Sheepshanks gave his collection to the South Kensington Museum (later the Victoria and Albert Museum), known for years as the National Gallery of Art (the same title as the Tate Gallery had). Forty years later Sir Henry Tate who was a sugar magnate and a major collector of Victorian Art, offered to fund the building of the gallery to house British Art on the condition that the State pay for the site and revenue costs. Henry Tate also donated tis own collection to the gallery. It was initially a collection of modern British art, concertrating on the works of modern painters. It was controlled by the National Gallery until 1954.
