the tallest of which was high and which was abandoned in 1932. After 1947 Agecroft Colliery sent much of its coal to the CEGB's Agecroft Power Station, via a conveyor belt system that crossed a bridge over Agecroft Road. Mining finished in 1990, and the Agecroft Colliery site is now home to the Agecroft Commerce Park. The Kearsley, Clifton, Pendlebury and Pendleton Miners' Association was established in 1888 and became the Pendlebury Branch of the National Union of Mineworkers in 1959. With the decline of the industry, the once popular Pendlebury Miners' Club (at the top of Temple Drive, Swinton) was demolished in the 1990s. Governance Pendlebury was joined with Swinton in 1875 to form a local board of health area and was later governed by the Swinton and Pendlebury Urban District Council. Incorporation of Clifton into the Municipal Borough of Swinton and Pendlebury was a result of the abolition of the predecessor, Barton-upon-Irwell Urban District. Swinton and Pendlebury was a municipal borough of the administrative county of Lancashire, which contained Pendlebury, Swinton and Clifton. It received a Charter of Incorporation from the 18th Earl of Derby on 29 September 1934 at a ceremony in Victoria Park, Swinton when council meetings were held in Victoria House in the park. The new borough council required larger premises and launched a competition to design a new town hall. The winners were architects Sir Percy Thomas and Ernest Prestwich. The site of Swinton Industrial Schools on Chorley Road in Swinton was purchased for £12,500 and the foundation stone of the new town hall laid on 17 October 1936. It opened on 17 September 1938 and since 1 April 1974 has been the administrative headquarters of the enlarged Salford City Council.

In terms of parliamentary representation, the town was until 2010 part of the Eccles constituency. Since then it has been part of the Salford and Eccles constituency. Geography Pendlebury is situated on a ridge overlooking the lower Irwell Valley, almost midway between Manchester and Bolton and is neighboured by Irlams o' th' Height, Pendleton and Clifton.
