Greenwich (UK ⁱ/ɡrɪnɪdʒ/ GRIN-ij; US /ɡrɛnɪtʃ/ GREN-ich or /ɡrɛnɪdʒ/ GREN-ij) is a district of south London, England, located in the Royal Borough of Greenwich and 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 in the House of Tudor, including Henry VIII and Elizabeth I. The palace fell into disrepair during the English Civil War and was rebuilt as the Royal Naval Hospital for Sailors by Sir Christopher Wren and his assistant Nicholas Hawksmoor. These buildings became the Royal Naval College in 1873, and they remained an establishment for military education until 1998 when they passed into the hands of the Greenwich Foundation. The historic rooms within these buildings remain open to the public; other buildings are used by University of Greenwich and the Trinity College of Music.
