Greenwich is a town in south-east London, England. Greenwich is notable for its maritime history and for giving its name to the Greenwich Meridian (0° longitude) and Greenwich Mean Time. The town became the site of a royal palace, the Palace of Placentia from the 15th century, and was the birthplace of many Tudors, including Henry VIII and Elizabeth I. The palace fell into disrepair during the English Civil War and was demolished to be replaced by the Royal Naval Hospital for Sailors.
The town became a popular resort in the 18th century and many grand houses were built there, such as Vanbrugh Castle (1717) established on Maze Hill, next to the park. From the Georgian period estates of houses were constructed above the town centre. The maritime connections of Greenwich were celebrated in the 20th century, with the siting of the Cutty Sark and Gipsy Moth IV next to the river front, and the National Maritime Museum in the former buildings of the Royal Hospital School in 1934.
