the local market once consisted of 400 stalls and was one of the busiest in yorkshire and in years gone by drew large numbers of visitors to the town. wednesdays and saturdays are the normal market days with the popular flea market on fridays. the town's mills were located just south of the river calder in the town centre. as the mills closed this area became a large brownfield site. however, many of the units have been reoccupied and the town's largest employer, carlton cards, is based in this area.
