Chorley is a market town in Lancashire, in North West England. It is the largest settlement in the Borough of Chorley. Chorley is located 8.1 miles (13 km) north of Wigan 10.8 miles (17 km) south west of Blackburn, 11 miles (18 km) north west of Bolton 12 miles (19 km) south of Preston and 19.5 miles (31 km) north west of Manchester. As in much of Lancashire, the town's wealth came principally from the cotton industry, although it also became a major market town due to its central location between four other towns. As recently as the 1970s the skyline was dominated by numerous factory chimneys, but most have now been demolished: remnants of the industrial past include Morrison's chimney and a few other mill buildings, and the streets of terraced houses for mill workers. Chorley is the home of the Chorley cake. Chorley's population increased from 31,556 in 2001 to 34,667 in 2011.
