In 1500, a year before the construction of the new Richmond Palace began, the name of the town of Sheen, which had grown up around the royal manor, was changed to "Richmond" by command of Henry VII. However, both names, Sheen and Richmond, continue to be used, not without scope for confusion. Curiously, today's districts of East Sheen and North Sheen, now under the administrative control of the London Borough of Richmond upon Thames, were never in ancient times within the manor of Sheen, but were rather developed during the 19th and 20th centuries in parts of the adjoining manor and parish of Mortlake. Richmond remained part of the County of Surrey until the mid-1960s, when it was absorbed by the expansion of Greater London.
