About The O2
On the Greenwich Peninsula in southeast London, the O2 Arena, also referred to as the O2, is a multi-use indoor arena in the heart of the O2 entertainment complex. It debuted in this version in 2007. In 2008, it was the busiest music arena in the world and has the second-highest seating capacity of any indoor venue in the UK, after the Manchester Arena.
The Millennium Dome, a sizeable dome-shaped structure constructed to house an exhibition commemorating the turn of the third millennium, served as the foundation for the arena's construction. Since the building still stands over the arena, the name "The Dome" is still frequently used to refer to the location. The arena and the entire O2 complex bear the name of the event's principal sponsor, the telecoms firm O2, a division of Virgin Media O2
