Summary

Lying on a field known as 'Bruffs', approximately 450m to the SE of Great Givendale on the western edge of the Yorkshire Wolds, a univallate contour fort of 3.1ha. It was recorded as a shadow site and cropmarks on an aerial photograph taken in 1958. Its location at 158m OD on the summit of a hill would have offered a commanding position over a wide expanse of the Vale of York to the W and S. The site was circular in plan and a survey in 1959 showed the rampart survived between 1.2-1.5m high in woodland to the N, but was plough levelled elsewhere (Dymond 1959). Quarrying had destroyed all traces of the ramparts in the S. The site was first noted by Phillips (1855) and then through the discovery of a La Tne period inhumation complete with Iron sword, shield and spearhead in a chalk pit in 1868 (Mortimer 1869) now known to have been part of the hillfort. Three further unaccompanied burials were discovered. Further excavations in 1961-2 (Stead et al. 1968) sectioned the ditch along nine points showing it to be rounded in profile, 1.8-2.1m deep and 3-4.5m wide. A berm 3.7-4.6m wide lay on the inside of the ditch beyond which was a levelled rampart marked out by two rows of postholes spaced at intervals of between 1.8-3m, for a timber frame, which would have contained chalk blocks. Blocks from the ramparts found within the ditch fill were interpreted as an act of deliberate slighting, with the wall pushed into the ditch. A causeway 3.7m wide lay in the SE giving access to a stream and springs. On either side of this the ditch was found to be wider and more flat-bottomed than elsewhere. However postholes in this region continued without a break. A crouched burial and a large quantity of Iron Age pottery and animal bone was recovered, mainly from the ditch. Medieval and Romano-British pottery and a sherd of a Bronze Age collared urn came from the surface of the interior. The excavations also showed that the plough had obliterated any features within the enclosure, with only those around the margins of the rampart surviving. Amongst these are four eight four-post structures interpreted as granaries, although no evidence for storage pits was found. The site is not recorded on OS mapping.
