Monument Types


Cow Castle is labelled on the 2nd Edition Ordnance Survey map at SS 7944 3734. [1]

Cow Castle is a univallate hillfort of under 3 acres in size, sited about 200 feet (approximately 60.96 metres) above a bend of the River Barle. The bank is up to 10 feet (roughly 3.05 metres) high with an outer ditch, except where the slope makes this unnecessary. The entrance was on the southeast, and on the northeast there is a modern opening through the rampart. (2-4)

Cow Castle occupies a defensive position encircling a knoll which lies in a broad, steep sided valley. The hillfort consists of a single rampart (some fragments of the retaining wall still survive) beyond which, on the north and west, is a berm. The gap in the northeast is probably modern, that in the southeast is original. [5]

Cow Castle, at SS 795374 is scheduled (Listed under heading Camps and Settlements). [6]

Cow Castle covers 0.9 hectares and is at a height of 235 metres Ordnance Datum. The defences consist of a mostly flat topped bank, which is apparently stone revetted both inside and out. There is a silted ditch around the circuit. Burrow recorded: "The entrance gap on the southwest is about 3 metres wide and the passage formed by the inturned ramparts is 9 metres deep, with vertical revetment stones visible on the south side". (There is no entrance gap or inturned ramparts shown on the southwest on the plan by Palmer. Perhaps Burrow refers to the entrance on the southeast). The interior has very steep slopes on the west and north, but slopes more gently on the other two sides, and there are possible hut platforms on the east side. [5, 7]

Grinsell considers the original entrance to be in the northeast, but he says Rainbird Clarke thought it to be in the southeast where there is a small standing stone which could have formed part of its stonework. Allcroft mentions that the site is called Cow or Cae Castle. [8-9]

Cow Castle, at SS 794 373, is listed in the gazetteer as a univallate hillfort covering 1.1 hectares. [12]

Cow Castle, a univallate hilltop enclosure presumably of Iron Age date, is centred at SS 7945 3735. It occupies a steep sided isolated knoll within the valley of the River Barle at its confluence with White Water, and therefore dominates the Barle valley.
The enclosure has an internal area of 1.2 hectares, most of which is on sloping ground. It is defined by a rampart up to 2 metres in height with an external berm 4.5 metres wide. On the southern side of the enclosure a stone revetment is visible on the external face of the rampart, and where it is best preserved, it survives as a coursed stone wall 0.8 metres high. A quarry ditch 5 to 7 metres wide follows the inner side of the rampart for most of its circuit.
The enclosure has a single entrance, 8 metres wide, on the eastern side. The ramparts are noticeably higher on either side of the entrance, and the terminals have been heightened further. The northern one appears to be T-shaped or to turn both outwards and inwards. The same effect is noticeable though less pronounced on the southern terminal. An upright stone is visible on the external corner of the southern terminal, it is 0.65 metres high, 0.6 metres long and 0.2 metres thick.
It has been previously reported that there are at least four house platforms within the enclosure on the northern side. These were not visible due to dense bracken. However, a slight platform was noticed at the northwestern end of the enclosure, and there are several natural terraces on this side which would have been convenient locations for settlement. The quarry ditch may also have been used for buildings. [13]

A large scale survey was undertaken by the Exeter Office of the RCHME for the Exmoor National Park Authority and as part of the RCHME Exmoor Project in May 1997. The site was surveyed using GPS at a scale of 1:1000. The sites of probable prehistoric habitation were recorded, and an earthwork survey, contour plan and digital terrain model were produced.
The defences form an oval enclosure 0.6 hectares in area. They comprise a single rampart and external ditch which is best defined as it approaches the two entrances. The rampart is 1.6 to 1.8 metres high externally and 1.5 to 2 metres thick. The outer face is revetted in stone. Of the four gaps in the rampart, the northeast and southeast are considered to be original. Both comprise a simple passage through the rampart which is enlarged at either side. The interior is steep, but there are several locations behind the rampart and on terraces where habitation might be expected. To the north of the hillfort a well defined scarp may represent access to a quarry to the northeast. This may be associated with mineral prospection. [14-22]

Three possible entrances and a building inside can be seen on aerial photographs. [23]

The univallate hillfort of Cow Castle is clearly visible on aerial photographs examined as part of the Exmoor National Park National Mapping Project in 2008. The platforms described by Wilson-North and Chapman, however, are not discernible. [13, 28-29]

The Scheduled Monument Condition Assessment of 2009 records Cow Castle as being in poor condition and at high risk. It has suffered significant damage from bracken and is slowly deteriorating. [30]

The original entrance to the monument is to the southeast, the current entrance in the northeast is post-medieval, possibly connected to the nearby quarry pits. The location of the site did not require the creation of a continuous ditch, as the area benefits from natural defences. The site location may have been strategic, with iron and copper ore nearby, and access to the river. The monument may have been used after the Iron Age for meetings or sporadic defence as required.
