One of the largest conservation areas in Manchester, Castlefield is situated on the south-west side of the city centre. Its focus is the Roman fort from which it derived its name - i.e. 'castle in the field'.
Before designation, the Department of the Environment (now called the Department of Culture, Media and Sport) declared an intention to elevate Castlefield to the status of an outstanding conservation area, which they did in January 1980. Although this status has since been abolished nationally, it is indicative of the area's importance.
Designated on 13 October 1979, the conservation area's boundary follows that of the city along the River Irwell, New Quay Street, Quay Street, Lower Byrom Street, Culvercliff Walk, Camp Street, Deansgate, Bridgewater Viaduct, Chester Road, Arundel Street, Ellesmere Street, Egerton Street, Dawson Street and Regent Road. On 26 June 1985 the area was extended by the addition of land bounded by Ellesmere Street, Hulme Hall Road and the River Irwell.
