The 2012 Olympic and Paralympic Games will use a mixture of new venues, existing and historic facilities, and temporary facilities, some of them in well-known locations such as Hyde Park and Horse Guards Parade. In the wake of the problems that plagued the Millennium Dome, the organisers' intention is that there will be no white elephants after the Games and instead that a "2012 legacy" will be delivered. Some of the new facilities will be reused in their Olympic form, while others, including the 80,000 seater main stadium, will be reduced in size or relocated elsewhere in the UK. The plans are part of the regeneration of Stratford in east London which will be the site of the Olympic Park, and of the neighbouring Lower Lea Valley.
