Dunster occupation. These include Bat's Castle and Black Ball Camp on Gallox Hill, Long Wood Enclosure and a similar earthwork on Grabbist Hill. Dunster is mentioned as a manor and Dunster Castle as belonging to William I de Moyon (alias de Moion, also de Mohun) in the 1086 Domesday Book. After the Norman conquest of England in the 11th century, he constructed a timber castle on the site as part of the pacification of Somerset. A stone shell keep was built on the motte by the start of the 12th century, and the castle survived a siege during the early years
Dunster Castle Conygar Tower, was constructed by architect Richard Phelps to improve the view from the castle, and a larger park of 141 hectares (348 acres) was built just to the south of the castle, requiring the eviction of a number of tenant farmers. Henry's son, John, inherited the castle in 1780, but when his son, also called John, inherited in 1816 he chose to live in London instead, opening up Dunster Castle to the public. By 1845 the castle appeared to visitors to be past its prime: with only two of John's sisters living there and no horses or hunting dogs
