The English city of Bristol has a number of parks and public open spaces.
Bristol City Council own or manage four major parks: The Downs, Blaise Castle, Ashton Court and Stoke Park.
The Downs lie 2 miles (3 km) northwest of the city centre and totals 441 acres (1.78 km2). The Downs are divided into Clifton Down to the south and Durdham Down to the north, with a main road running between them. At the south end of Clifton Down is the Clifton Suspension Bridge, and both look over the Avon Gorge. The Downs are protected by an 1861 Act of Parliament, and are managed by the Downs Committee, a joint committee of the city council (which owns Durdham Down) and the Society of Merchant Venturers (which owns Clifton Down).
Blaise Castle estate, situated 4 miles (6 km) north west of the city centre, includes a recreation ground and large playing fields, as well as woodland, a mansion, and a small gorge, totalling 650 acres (2.6 km2). The mansion house is now a branch of Bristol City Museum and Art Gallery.
At 850 acres (3.4 km2) Ashton Court estate is Bristol's largest park. Though the estate lies largely within the boundaries of North Somerset it is maintained by Bristol City Council, and has been publicly owned since 1959. The park contains horse riding and mountain biking trails, and is protected as a Site of Special Scientific Interest for its ecology. The mansion house is now a conference centre.
Stoke Park is Bristol's newest park, acquired by Bristol City Council in 2011 and occupying a prominent position alongside the M32 motorway.
