Monument record MDO4615 - Shaftesbury Castle, Castle Hill, Shaftesbury

A triangular enclosure at the western end of the Greensand Ridge upon which the burh of Shaftesbury was built. The site was excavated between 1947 and 1949. It is thought to represent the site of an unlicensed castle constructed during the reign of King Stephen.

A probable Norman fortified farmhouse and the site of an Adulterine Castle. The earthwork is surrounded by steep natural slopes on all but its eastern side where a ditch up to 18 metres wide and with an average depth of 2 metres has been cut to complete the all round defence. The inner bank in this quarter varies between 13 metres and 17 metres wide and has an average height of 1 metre. There is a pit in the centre. Excavations in 1947-9 discovered three tripod pitchers dating from the 12 to 13th centuries. There seems to have been a castle on Castle Green, a little west of St. Mary's. The site is also called Boltbury and is the traditional site of the old town (a). Castle Hill is a small steep promontory at the west end of the hill on which Shaftesbury stands. A deep artificial ditch has transformed the promontory into a triangular enclosure. There is an inner bank along all three sides. The interior is level, except for a large pit, dug much later than the rest of the earthworks. It has sometimes been suggested that the pit was caused by the removal of a free-standing tower. There is no sign of a motte and no documentary evidence of a properly constituted castle. The enclosure was trenched by E.Jervoise, 1947-9, and the following finds made, now in Shaftesbury Museum: The remains of three tripod pitchers of 12th-13th c. and a halfpenny of Stephen; the latter came from a trench dug in the bottom of the pit - Cobbler's Pit. From the finds the site would seem early Md., possibly 12th c. There was no evidence to show EIA or Civil War construction. Listed as a moated mound with probable shell keep. <1-2> <4-5> The earthwork is surrounded by steep natural slopes on all but its eastern side where a ditch up to 18.0m. Wide and with an average depth of 2.0m. Has been cut to complete the all round defence. The inner bank in this quarter varies between 13.0 and 17.0m. Wide and has an average height of 1.0m. Elsewhere it is considerably weaker and fades to nothing in parts. The earthwork is otherwise as described by Authy 3. The pit referred to is steep sided and is up to 3.0m deep. There is no visible indication of a motte, entrance or stonework. The position and nature of the fortification, the dateable material found and lack of documentary evidence suggest that this was an adulterine castle. It is under grass. <6> This is the site of a fortified Norman farm-house with three walls and two angle towers. It has been excavated and is now a garden. A small motte and bailey existed to the east. <7> Published survey (OS 25", 1901) revised. <8> ST 856228. A ditch and platform which represent the remains of a former castle, plausibly a temporary fortification dating from the 12th century Civil war. The site is overgrown and disturbed by former excavations and near the middle is a rectangular pond about 10ft deep. A crescent-shaped ditch up to 65ft. Wide and 15ft deep separates the spur from the higher ground on the east. Earthworks within the area include a low bank on the south west a roughly rectangular mound about 1 1/2ft. High on the east and some roughly rectangular platforms of varying size; the triangular area is artificially scarped above the natural slopes of the spur. <10> Listed as small ringwork by Cathcart King & Alcock <9> and as possible Norman Castle by Renn <11>. Listed by Cathcart King as a ringwork. <12>
