Chelsea is an affluent area known for its smart boutiques, high-end restaurants lining the King's Road and hosting the world's famous Chelsea Football Club. The National Army Museum traces British army history from the 1600s to the present, while the Saatchi Gallery displays contemporary art in the Duke of York's headquarters. The red-coated retired soldiers known as the Chelsea Pensioners run guided tours of their residence, the Royal Hospital Chelsea. Chelsea is in the Royal Borough of Kensington and Chelsea, and includes the postcodes SW3 and SW10. It started life as a village, and in the 19th century it transformed into a riverside resort and became popular with artists: Victorian painters Dante Gabriel Rossetti, J.M.W. Turner and James Whistler all resided here. During the 1960s, London’s "Swinging" years, Chelsea and King’s Road was a true hot spot.
