The National Hockey Stadium was a sports stadium in Milton Keynes with a nominal capacity of around 4,000 seats: this was temporarily increased to 9,000 between 2003 and 2007. It was used by England Hockey as their national stadium from 1995 to 2003 and then as a professional football stadium by Wimbledon FC, rebranded as Milton Keynes Dons in 2004. In summer 2007, the Dons relocated to the new Stadium MK, near Bletchley, leaving the hockey stadium without a tenant. It was unused for two years and, in late 2009, demolition began in preparation for the redevelopment of the site into the new Network Rail headquarters which became operational in July 2012. Hockey The stadium was built in 1995 as a new national field hockey stadium, with a synthetic pitch. The ground was used for national and international (field) hockey until 2003. It had a covered main stand running the full length of one side of the pitch, opposite which was an unroofed stand running about one third of the length of the pitch, straddling the halfway line. In 1997, the stadium was used as the venue for the sixth edition of the FIH Men's Junior World Cup. It was also the venue, in 2000, for the FIH Women's Qualifying Tournament for the Sydney 2000 Olympic Games. In 2003, after the ground was leased to Wimbledon FC, a grass pitch was laid, meaning that the stadium was out of commission for hockey. Temporary stands were added at either end of the pitch. Hockey internationals and playoff matches were reallocated to various leading club grounds around the country. In May 2007, at the end of the lease, the temporary stands were removed. On 2 April 2007, the trustees of the National Hockey Foundation, which owned the lease of the stadium, announced that they had arranged to hand the lease back to English Partnerships. A detailed study had shown that the stadium would no longer be viable as a hockey venue, especially as plans were in place to build the Olympic Hockey Centre in Stratford, London, as part of the 2012 Summer Olympics facilities. Football The stadium was the home of Wimbledon FC (rebranded Milton Keynes Dons in June 2004) from September 2003 until May 2007. The Dons converted the synthetic pitch to grass and added additional stands and seating (with up to 9,000 seats). In July 2007, they moved to the
