Calder Vale is an English village, located on the edge of the Forest of Bowland in Lancashire. It lies on the River Calder in a deep valley with only a single road providing access to it. The name Calder is thought to be derived from the Old Norse "kaldr" (cold).The village was founded by Quakers Jonathan and Richard Jackson, and in 1835 a cotton-weaving mill — the Lappet Mill — was built, powered by the River Calder.
