The City of Manchester Stadium, also known as COMS or Eastlands,  is a stadium in Manchester, England. Originally designed as part of Manchester’s failed bid for the 2000 Summer Olympics, the stadium was built for the 2002 Commonwealth Games at a cost of ?110 million. After the Games, it was converted for use as a football ground and became the home of Manchester City F.C., which moved there from Maine Road in 2003 after signing a 250-year lease.

The stadium is bowl-shaped, with two tiers all the way around the ground and a third tier along the two side stands. As of 1 July 2009, it is the fourth-largest stadium in the FA Premier League and the 12th-largest in the United Kingdom, with a seating capacity of 47,726. On 14 May 2008, it hosted the UEFA Cup Final.

Plans to build a stadium in east Manchester were formulated around 1990 as part of the city’s bid to host the 2000 Summer Olympics; Manchester City Council commissioned a design for an 80,000 capacity stadium on a brownfield site known colloquially as Eastlands. However, in October 1993 the games were awarded to Sydney, Australia. Manchester subsequently made a successful bid to host the 2002 Commonwealth Games, using the stadium plans from the Olympic bid. In 1996, the planned stadium competed with Wembley Stadium to gain funding to become the national stadium, but the money was used to redevelop Wembley. The stadium’s foundation stone was laid by Prime Minister, Tony Blair, in December 1999, and construction began in January 2000. The stadium was designed by Arup and constructed by John Laing at a cost of approximately ?110 million, ?77 million of which was provided by Sport England, with the remainder funded by Manchester City Council. For the Commonwealth Games, the stadium featured a single lower tier running around three sides of the athletics track, and second tiers to the two sides, with an open-air temporary stand at one end. The first public event at the stadium was the opening ceremony of the 2002 Commonwealth Games on 25 July 2002. Among the dignitaries present at the ceremony was Queen Elizabeth II. During the ten days of competition, the stadium hosted all athletics events and the rugby sevens. Four Commonwealth records were set at the stadium, including the women’s triple jump and the women’s 5000 m.
