Longridge initially developed outwards from an area around St. Lawrence's Church, at the boundary of the townships of Dilworth and Alston and to the south of the modern-day town centre. Though there was a thoroughfare called 'Market Place', there was no development around that area. Most of the development of the town occurred after 1800. After this time, development occurred at a much faster pace, with expansion northwards including a mill to the north of Kestor Lane. The demand for stone from Longridge's quarries led to the opening of the Preston and Longridge Railway in 1840 to carry the stone away, for use in such places as Liverpool Docks. The arrival of the railway led to the opening of several cotton mills and the town grew considerably larger from the mid-19th century. The mills and quarries have now all closed, although stone quarried in the town was used to construct the M55 motorway in the 1970s. One of the quarries was used as Longridge motor-racing circuit between 1973 and 1978. Longridge railway station closed to passengers in 1930, and the railway was dismantled in 1967. The station buildings were then used as offices for the parish council until 2010 when the Longridge Town Council began a project to renovate and reopen the buildings to the public with help from the Lottery Heritage Fund. Longridge railway station is now managed by Longridge Social Enterprise Company and is home to a heritage centre, the Old Station Cafe and has various business facilities available.
Housing
The appearance of the town centre has changed little from when it was first built. Many of the buildings are built of locally quarried sandstone and despite more modern developments the town centre remains largely as it was when it was first developed. The town itself has expanded since the closure of the quarries with the building of new housing estates, as well as council housing.
Community
The town is home to eleven pubs, several restaurants, a public library, and a number of primary and high schools. It is also home to an Air Training Corps squadron and an Army Cadet Force detachment. Longridge is also the location of Alston Hall, a residential adult education college operated by Lancashire Adult Learning. The local football club, Longridge Town F.C., has two senior teams and plays in the NWCFL, at Step 6 of the FA Football Pyramid. Its ground and clubhouse are situated off Inglewhite Road, behind the Alston Arms.
