Victoria&Albert Museum:

Someone once asked me what was at the Victoria & Albert Museum and all I could say was “stuff.” The website says: “V&A South Kensington is the world’s greatest museum of art and design, with collections unrivalled in their scope and diversity. Discover 3000 years’ worth of amazing artefacts from many of the world’s richest cultures including ceramics, furniture, fashion, glass, jewellery, metalwork, photographs, sculpture, textiles and paintings.” I should have said “cool stuff” or “lot’s of stuff.” It’s also free.
