Cassop

Cassop (formerly New Cassop) is a village in County Durham, in England. It has a population of about 500 and is located near the city of Durham. A former mining village, mining is no longer the main occupation of Cassop's inhabitants due to extensive mine closure over the last 30 years.Formerly this village was in the parish of Kelloe, but like many of the villages in that extensive parish, it broke away during the 19th century in this case to form the parish of Cassop-cum-Quarrington, with the neighbouring village, Quarrington Hill.

It lies between the villages of Bowburn and Cassop, 7 km south-east of the centre of Durham..The site is important as one of the larger areas of grassland developed on magnesium limestone. This rock has a restricted distribution in England and grassland associated with it is confined almost entirely to south-east Tyneside and County Durham, usually in small, scattered patches that are threatened by quarrying and modern agricultural practices.
