The Royal Borough of Kensington & Chelsea has always been home to world-famous movers and shakers. There are more blue plaques (historic markers) here than in any other part of London, three superb shopping districts, a royal palace, and one of the best concentrations of museums in the world. Kensington is the more established, conservative area, while Chelsea, equally well-heeled, basks in its literary and artistic connections: the youth culture of the '60s was virtually invented here. Today, though more comfortable than cutting-edge, it still attracts fascinating people to its villagelike neighborhoods.
