Full Description

'Bat's Castle Camp' is marked on the 1962 Ordnance Survey map. [1] Bat's Castle is an approximately circular enclosure with two banks of stone and a ditch between, situated on a hilltop. The hill is steep on the north and south, but fairly level on the east and west. One entrance is on the west, where the bank turns inwards to flank the passage. On either side there are remains of masonry, but the mortar is modern in character. The other entrance on the east, is peculiar, with the pathway continuing eastwards for c.25 yards as a raised platform, with a ditch along each side and an outer bank. On each side of this entrance are indications of shallow pits, very like rifle pits which have been dug in the outer surface of the bank. [2] Bat's Castle is a univallate hillfort (under 3 acres). [3] 'Bat's Castle' is a hill-slope enclosure with strong defences, which bring it into the category of a small hill-slope fort. Bothamley's description of the entrances is inaccurate. That on the west is slightly clubbed with some modern mutilation. No mortared masonry is now visible. The unusual east entrance with its flanking banks and ditches is also inturned. The 'rifle pits' recorded by Bothamley are insignificant. It is probable that the earthwork to the east (MSO9083) is associated with this hillfort. Surveyed at 1:2500. [5] Bats Castle (at SS 988 421) is a strongly defended Iron Age univallate hillfort on a hill crest. The east entrance is unusual, and from air photographs does not appear to be original. The interior appears featureless, with traces of 19th century ploughing visible on aerial photographs. [6] The west entrance is inturned with a very deep ditch. The east entrance is astride the ridge and does not appear to be original. The inner banks are slightly inturned, but the terminals of the ditch turn east for about 45 metres, flanking a causeway 6 metres wide (maximum). The ramparts have been damaged in several places and partly pushed forward into the ditch. (Visited by Burrow 04/04/1973.) [7] Black Ball Camp (MSO9410) may be a satellite of Bat's Castle. The earthwork to the south-east (MSO9083) together with Bat's Castle forms a probable crossbank enclosure. [8] Rainbird Clarke (in about 1938-9) claimed that the eastern entrance and southern outworks (MSO9083) of Bats Castle were civil war additions, for the seige of Dunster Castle (MSO9412). Bats Castle was called Caesar's Camp by Page. [9] Savage describes the bank as 'terraced-like steps'. [10] Bat's Castle was surveyed at 1:1000 scale using GPS as part of the RCHME Exmoor project. The site lies on the hilltop between Gallox Hill and Withycombe Hill, at 200 metres Ordnance Datum. A small hillslope enclosure lies on Gallox Hill 600 metres to the northwest (MSO9410). The outwork to the southeast of Bat's Castle was also surveyed (MSO9083).The defences enclose a sub-rectangular area of 140 x 100 metres. They consist of a rampart and ditch with a strong counterscarp bank. The overall width of the defences is some 20-25 metres. The ramparts are very stony, with much loose material on the surface, and it would appear that stone extraction has taken place in the past. This would account for the rifle pits and 'tourelles' described by Allcroft and Bothamley. [12,13] There are two original entrances. The western entrance is a simple passage through the defences, with an inturn to the south. The eastern entrance is more complex. The inner ramparts thicken and inturn. The ditch and counterscarp turn sharply away from the hillfort to form a causeway 50 metres long and 6 metres wide. There is no reason to suppose that this entrance is later than the main defensive work, as suggested by Burrow and Rainbird-Clarke. A third breach of the defensive circuit is caused by the well established track which runs between the two enclosures to Withycombe Hill Gate. [21] A small multivallate hillfort with an associated cross-ridge outwork (MSO9083). It is roughly circular, enclosing 1.2 hectares, at one end of the summit of a gently-sloping hilltop, with a steep drop on the southwest side. It is intervisible with smaller contemporary enclosures in the area. Defences consist of an inner and outer rampart, of rubble, surviving up to 2 metres high, separated by a ditch up to 2 metres deep. There are two entrances: on the west is a simple gap and causeway; on the east the inner rampart is inturned and the ditch and outer bank turn out to flank a 45 metre approachway. This approachway appears to be a later alteration. There are slight ridges and furrows in the interior that may be recent as the fort was used to grow potatoes in WWII. It is suffering very seriously from visitor erosion. There are possibly contemporary settlement and fields to the southeast (MSO11705). [24] The ridges are not visible on 1947 air photographs. [25] The hillfort of Bat's Castle and associated outwork were clearly visible on aerial photographs surveyed as part of the Exmoor National Park National Mapping Programme. [22,25] The internal diameter is 300 feet. The ramparts rise 1.65 metres above the interior, with a ditch of c1.8 metres deep. Patches of loose stone are exposed in the ditch and on the ramparts. A track crosses the site from northwest to southeast using a causeway to the entrance on the west side, and crossing banks where they are lowest on the southeast and where the ditch is infilled. The track has a stony base. [26] Also, there are two lengths of banks with ditches to the northeast, which may be an outwork. [27] Some coins were discovered at the end of 1983, by two schoolboys playing on the ramparts who then dug to find the remainder of a coin hoard. The hoard was spread over an area of 2 square metres and comprised eight coins with a large date span from 102 BC to 350 AD. Three of the coins, which were silver plated, were declared treasure trove at an inquest on the 9th September 1986. [31] Bat's Castle was re-scheduled on the 25th February 1994 with a new national number (old number was Somerset 245a). [36] There is a substantial bank and ditch on the east side, with some infilling and holes in the bank. Some areas of stone are exposed, with evidence of both human and animal disturbance. The causeway on the northeast side is c9 metres across. There is a recent hole in the southeast entrance. There is some horse damage along the track, which passes through the centre of the site; otherwise it has a good vegetation cover of heather, bracken and grass. There is no evidence of any ridge and furrow or hut circles. [40] The Scheduled Monument Condition Assessment of 2009 gave the site a survival score of 10. [42] Vegetation clearance of the main enclosure was undertaken in January 2009. [43] A digital reconstruction drawing was created in 2013 by Peter Lorimer. [44] The site was surveyed in May 2015 as part of the 2015 Exmoor Scheduled Monument Condition Assessment. It was given a survival score of 10. [45] The site is marked as "Bat's Castle" on the 1 inch 1898 Ordnance Survey map and as "Bat's Castle (Camp)" on the 25 inch map from 1889. [46-8]
