Take the Horniman Museum, in deepest, darkest Forest Hill. It's an absolute gem, but you've probably never even heard of it. It's easily one of the most eclectic museums in the UK: there's an aquarium, an exhibition dedicated to African culture, a vast collection of musical instruments and enough Victorian pickled creatures to satisfy even the most gothic of morbid tastes. Oh, and the stuffed Walrus has to be seen to be believed.

Vying for the eclecticism title is the Sir John Soanes Museum. Soanes spent his life indulging his twin passions - architecture and collecting art and antiquities and demolished and rebuilt three houses in Lincoln's Inn Fields to create a permant home for his collection which, thanks to the fact he fell out with his sons, is permanently open to the public.
