The O2 Arena

The O2 Arena is a multi-purpose indoor arena located in the centre of The O2 entertainment complex on the Greenwich Peninsula in south east London. The 20,000-seat arena was built under the former Millennium Dome, a large dome shaped building built to house an exhibition celebrating the turn of the third millennium; as the dome shaped structure still stands over the arena, The Dome remains a name in common usage for the venue. The arena, as well as the total O2 complex, is named after its primary sponsor, the telecommunications company O2.
