Natural History Museum
The Natural History Museum in South Kensington is perhaps the largest and most spectacular of all London's varied museums.
It contains no exhibits created by Man — just the works of Nature. This includes items as varied as dinosaur skeletons, blue whales, meteorites, minerals, and more.
Even the building, known as the Waterhouse building, is worth visiting as it features similar high Victorian architecture to St Pancras Hotel and an excellent cast-iron roof. The new Darwin Centre next door features more modern architecture, having been completed in 2003.
Currently entrance to this and many other London museums is free, but you are encouraged to make a donation, and have to pay for electronic tours.
Address: Cromwell Road, London, SW7 5BD
