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 London Borough Council which meets in Woolwich Town Hall. The council's offices are also primarily based in Woolwich, the primary urban centre within the borough. It covers an overall area of 18.28 square miles.
In accordance with population estimates during 2014, the borough features a permanent population of around 268678 people. The Prime Meridian running through Greenwich along with the Greenwich Observatory is exactly where the designation Greenwich Mean Time, or GMT began, and on which all world times are primarily based.
Greenwich was among six host boroughs for the 2012 London Olympics and events were held at the Royal Artillery Barracks for shooting, Greenwich Park for equestrianism, plus the O2, the former Millennium Dome, for gymnastics and basketball. It is also the home borough of professional football club Charlton Athletic. To mark the Diamond Jubilee of Elizabeth II, Greenwich became a Royal Borough on 3rd February 2012. This is partly a consequence of its historic links with the Royal Family, and to its UNESCO World Heritage Site status as residence of the Prime Meridian.
