Greenwich ( GREN-itch, -ij, GRIN-) is an area in south-east London, England, within the ceremonial county of Greater London. It is situated 5.5 miles (8.9 km) east-south-east of Charing Cross. 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.
