the national museum of Britain, established in 1753. The main building is in Bloomsbury, London, and includes the famous reading room, a large round room that used to be part of the British Library. When the new library building was opened, the inner court that contained the reading room was redesigned by Norman Foster. Many well-known writers have studied and written their books there. The museum has one of the world's finest collections of art and ancient objects, including the Elgin marbles and the Rosetta Stone.
