South Brent
South Brent (population 2,822) is a large village on the southerly edge of Dartmoor, England, in the valley of the River Avon. The parish includes the tiny communities of Aish, Harbourneford, Lutton, Brent Mill, and several scattered farmhouses. It is 5 miles (8 kilometres) north-east of Ivybridge and 14 miles (22 km) east-northeast of Plymouth. On the high moorlands are numerous hut circles, rooms, and barrows, all dating from the Bronze Age. The estate of Brent belonged to Buckfast Abbey from the moment of the structure of the abbey in the early 11th century. It was bought at the Dissolution by Sir William Petre, a large receiver of monastic spoils in South Devon. South Brent was originally a woollen and market centre with two annual fairs. Brent Hill is the high hillside just outside the town from which it takes its name (Old English brant-- steep). On it are the damages of an old building, supposed to have been a church, and also of a windmill constructed regarding 1790.
