At Queen Victoria's behest, the State Rooms of Kensington Palace were opened to the public in 1899, on her 80th birthday. Since then it's been both a private residence for the royal family and a public museum. In fact, it's where Prince William lives with the Duchess of Cambridge and their three kids. Though you won't bump into them in the hallway, a visit here is still a fascinating window into the lives of royals past and present.
The London Transport Museum is a museum dedicated to the history of public transport in England's capital city. The museum has been housed at the Victorian Flower Garden, located in Covent Garden, since 1980.
