The Victoria and Albert Museum would be on my list. The Victoria and Albert Museum (often abbreviated as the V&A), in The Royal Borough of Kensington & Chelsea, London, England, is the world's largest museum of decorative arts and design, housing a permanent collection of over 4.5 million objects. Named after Prince Albert and Queen Victoria, it was founded in 1852, and has since grown to now cover some 12.5 acres (0.05 km2)[2] and 145 galleries. Its collection spans 5,000 years of art, from ancient times to the present day, in virtually every medium, from the cultures of Europe, North America, Asia and North Africa. The museum is a non-departmental public body sponsored by the Department for Culture, Media and Sport.
The holdings of ceramics, glass, textiles, costumes, silver, ironwork, jewellery, furniture, medieval objects, sculpture, prints and printmaking, drawings and photographs are among the largest and most comprehensive in the world.
