The Royal Borough of Greenwich is a London borough in south-east London, England. Taking its name from the historic town of Greenwich, the London Borough of Greenwich was formed in 1965 by the amalgamation of the former area of the Metropolitan Borough of Greenwich with part of the Metropolitan Borough of Woolwich to the east. The local council is Greenwich Borough Council.
Greenwich is World famous as the traditional location of the Prime Meridian, on which all Coordinated Universal Time is based. The Prime Meridian running through Greenwich and the Greenwich Observatory is where the designation Greenwich Mean Time, or GMT began, and on which all world times are based. In 2012, Greenwich was listed as a top ten global destination by Frommer's - the only UK destination to be listed.
Greenwich was one of six host boroughs for the 2012 London Olympics and events were held at the Royal Artillery Barracks (Shooting), Greenwich Park (Equestrianism) and The O2-former Millennium Dome (Gymnastics; Basketball). To mark the Diamond Jubilee of Elizabeth II, Greenwich became a Royal Borough on 3 February 2012, due in part to its historic links with the Royal Family, and to its UNESCO World Heritage Site status as home of the Prime Meridian.
