Calstock (Cornish: Kalstok) is a civil parish and a large village in south east Cornwall, England, on the border with Devon. The village is situated on the River Tamar 6 miles (9.7 km) south west of Tavistock and 10 miles (16 km) north of Plymouth.
The parish encompasses 5,760 acres (23.3 km2) of land, 70 acres (0.28 km2) of water, and 44 acres (0.18 km2) of the tidal Tamar. The parish had a population of 6,095 in the 2001 census.
As well as Calstock, other settlements in the parish include Albaston, Chilsworthy, Gunnislake, Harrowbarrow, Latchley, Metherell, Coxpark, Dimson, Drakewalls, Norris Green, Rising Sun and St Ann's Chapel.
There is evidence of human settlement in Calstock from Roman, or pre-Roman times, settlers attracted by the rich source of minerals, such as tin, in the area. A Roman fort, only the third known in Cornwall, was discovered next to the church in 2008.
In Saxon times Calstock was in the Kingdom of Cornwall, which resisted the spread of Wessex from the east. In 838 CE Wessex had spread as far as the Tamar, and a battle for independence was fought near Calstock. Following the Norman Conquest, Calstock manor was recorded in the Domesday Book. The Saxon manor (held by Asgar) was taken over, and in the 14th century became part of the Duchy of Cornwall: one of the 17 Antiqua maneria. At the time of Domesday Book (1086) the manor was held by Reginald from Robert, Count of Mortain. There were two and a half hides of land and land for 12 ploughs. Reginald held one virgate of land with 2 ploughs and 12 serfs. 30 villeins and 30 smallholders had the rest of the land with 6 ploughs. There were 100 acres of woodland, 3 square leagues of pasture and 3 pigs. The value of the manor was £3 sterling though it had formerly been worth £6.
One of the many maps available on A Vision of Britain through Time is one from the Ordnance Survey Series of 1900 illustrating the parish boundaries of Cornwall at the turn of the 20th century. This map blows up to show all the parishes and many of the small villages and hamlets.
