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 a 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 principle urban centre inside the borough. It covers a total area of 18.28 square miles.
In line with population estimates from the middle of 2014, the borough includes a permanent population of about 268678 inhabiants. Greenwich is most famously known as the traditional place of the Prime Meridian, on which all Coordinated Universal Time is 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, as well as 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.
