William had been granted 68 manors in the region and by 1086 had established a castle at Dunster; this would form both the "caput", or principal castle, for his new lands, and help guard the coast against the threat of any fresh sea-borne attack, as well as controlling the coastal road running from Somerset to Gloucestershire.

Dunster church was shared for worship between the monks of Dunster Priory and the parishioners, however this led to several conflicts between them. One outcome was the carved rood screen which divided the church in two with the parish using the west chancel and the monks the east. It was restored in 1875–77 by George Edmund Street. The church has a cruciform plan with a central four-stage tower, built in 1443 with diagonal buttresses, a stair turret and single bell-chamber windows. Dunster, in Exmoor National Park, has many listed buildings including 200 Grade II, two Grade I and two Grade II*.
