The O2 Arena (visually typeset in branding as The O₂ arena, referred to as North Greenwich Arena in context of the 2012 Summer Olympics and Paralympics) is a multi-purpose indoor arena located in the centre of The O2, a large entertainment complex on the Greenwich peninsula in London, England.

With a capacity of up to 20,000^[2] depending on the event, it is second largest arena in the UK after the Manchester Arena and one of the largest in Europe. In 2008, The O2 Arena took the crown of the world's busiest music arena from the Manchester Arena, a title which it had held since 2001.^[3]

Background to the arena[link]

Following the closure of the Millennium Experience at the end of 2000, the Millennium Dome was leased to Meridian Delta Ltd. in 2001, for redevelopment as an entertainment complex. This included plans for an indoor arena.

Construction of the arena started in 2003 and finished in 2007. Owing to the impossibility of using cranes inside the dome structure, the arena's roof was constructed on the ground within the dome and then lifted. The arena building's structure was then built around the roof. The arena building, which houses the arena and the arena concourse, is independent from all other buildings in The O2 and houses all the arena's facilities. The whole arena building takes up 40% of the total dome structure.

The seating arrangement throughout the whole arena can be modified, similar to the Manchester Arena.^[4] The ground surface can also be changed between ice rink, basketball court, exhibition space, conference venue, private hire venue and concert venue.

The arena was built to reduce echoing which has previously been a problem in many London music venues.^[5] The sound manager for U2, Joe O'Herlihy, worked with acoustic engineers to introduce measures such as sound absorbing material on the arena roof and the bottom of strategically placed seats to reduce echoing.

Despite The O2 arena's being open for only seven months of the year, the venue sold over 1.2 million tickets in 2007, making it the third most popular venue in the world for concerts and family shows narrowly behind the Manchester Arena (1.25 million) and Madison Square Garden in New York (1.23 million). In 2008, it became the world's busiest venue taking the crown from MEN Arena with sales of more than two million.^[6]

London ⁱ/ˈlʌndən/ is the capital city of England and the United Kingdom, the largest metropolitan area in the United Kingdom, and the largest urban zone in the European Union by most measures.^{[note 1]} Located on the River Thames, London has been a major settlement for two millennia, its history going back to its founding by the Romans, who named it Londinium.^[3] London's ancient core, the City of London, largely retains its square-mile mediaeval boundaries. Since at least the 19th century, the name London has also referred to the metropolis developed around this core.^[4] The bulk of this conurbation forms the London region^[5] and the Greater London administrative area,^{[6][note 2]} governed by the elected Mayor of London and the London Assembly.^[7]

London is a leading global city, with strengths in the arts, commerce, education, entertainment, fashion, finance, healthcare, media, professional services, research and development, tourism and transport all contributing to its prominence.^[8] It is the world's leading financial centre alongside New York City^[9][10][11] and has the fifth-largest city GDP in the world (and the largest in Europe).^[12] London has been described as a world cultural capital.^{[13][14][15][16]} It was the world's most visited city during 2011 ^[17][18] and London Heathrow is the world's busiest airport by number of international passengers.^[19] London's 43 universities form the largest concentration of higher education in Europe.^[20] In 2012 London will become the first city to host the modern Summer Olympic Games three times.^[21]

London has a diverse range of peoples and cultures, and more than 300 languages are spoken within its boundaries.^[22] In July 2010 Greater London had an official population of 7,825,200, making it the most populous municipality in the European Union,^[2][23] and accounting for 12.5% of the UK population.^[24] The Greater London Urban Area is the second-largest in the EU with a population of 8,278,251,^[25] while London's metropolitan area is the largest in the EU with an estimated total population of between 12 million^[26] and 14 million.^[27] London had the largest population of any city in the world from around 1831 to 1925.^[28]

London contains four World Heritage Sites: the Tower of London; Kew Gardens; the site comprising the Palace of Westminster, Westminster Abbey, and St Margaret's Church; and the historic settlement of Greenwich (in which the Royal Observatory marks the Prime Meridian (0° longitude) and GMT).^[29] Other famous landmarks include Buckingham Palace, the London Eye, Piccadilly Circus, St Paul's Cathedral, Tower Bridge, Trafalgar Square, Wembley Stadium, and Shard London Bridge. London is home to numerous museums, galleries, libraries, sporting events and other cultural institutions, including the British Museum, Natural History Museum, National Gallery, Tate Modern, British Library, Wimbledon, and 40 West End theatres.^[30] The London Underground is the oldest underground railway network in the world^[31] and the second-most extensive (after the Shanghai Metro).^[32]
