The British Museum is dedicated to human history, art and culture, and is located in the Bloomsbury area of London. Its permanent collection, numbering some 8 million works, is among the largest and most comprehensive in existence and originates from all continents, illustrating and documenting the story of human culture from its beginnings to the present.
The British Museum was established in 1753, largely based on the collections of the physician and scientist Sir Hans Sloane. The museum first opened to the public on 15 January 1759, in Montagu House, on the site of the current building. Its expansion over the following two and a half centuries was largely a result of an expanding British colonial footprint and has resulted in the creation of several branch institutions, the first being the British Museum (Natural History) in South Kensington in 1881. Some objects in the collection, most notably the Elgin Marbles from the Parthenon, are the objects of controversy and of calls for restitution to their countries of origin.
