London has one of the greatest concentrations of top-class museums in the world. Big names like the British Museum, the National Gallery and Tate Modern attract millions of visitors every year. Then there’s the hugely popular South Kensington cluster: the Natural History Museum and Science Museum, firm favourites with kids, and the Victoria and Albert Museum, with its second-to-none collection of decorative arts. But it’s not all about huge national museums. Smaller places present specialist, sometimes unique collections that are well worth a visit. Between all these options there’ll be a place catering to just about every interest a visitor to London could have, and with most of them free, and many of them offering late night openings with special events on offer, for a museophile it’s a case of where to stop, rather than where to start. Here we pick our cream of the crop to help you decide.
