Petrie Museum one of the most unusual in London

The Telegraph (John O' Ceallaigh)

It's not hyperbole to say that London is home to many of the world's best museums. Venues such as the British Museum, Victoria and Albert Museum, Science Museum and Design Museum can justly lay claim to being the best in their field (and most of them are free too). But with so many world-famous museums dominating the itineraries of tourists and being a first port of call for locals with visitors in tow, it can be easy to overlook London's cornucopia of lesser-known and smaller-scale museums. With that in mind I've rounded up 50 of the best unusual London museums for people looking for alternatives to the big hitters. I've termed them 'unusual' not because their subject matter is quirky or weird - although, sometimes, that's definitely the case - but because they're not typically the usual choice for newer visitors to the city.

Found within UCL, the Petrie Museum of Egyptian Archaeology may be small but its collection of some 80,000 objects makes it one of the greatest museums of its type anywhere.
