Summary

Lying within Ox Carr Wood on the west bank of the River Derwent, a univallate fort of 6.7ha on a promontory (possibly a promontory fort) (Oswald and Keenan unpublished). The site was first recorded on 1856 OS mapping and described as an intrenchment - a pre-Roman defensive earthwork. The discovery of large quantities of Roman pottery in nearby fields and the proximity to the Crambeck Roman pottery kilns led to the interpretation of the earthworks as Roman. The ditch of the earthworks in the S and E has been used for centuries as a trackway and the site is currently recorded as a Roman Camp and holloway (NMR No. SE76NW 1) and included in the scheduling Roman pottery kilns and associated features at Crambeck,. The description here as a hillfort is based on the recent survey and subsequent interpretations of Oswald and Keenan. The site comprises two sets of earthworks; one which follows the contours of the promontory in the S and E and a second which traverses the slopes to the N and W (described as 'cross-ridge' by the investigators) giving the enclosed area an approximately rectangular ground plan which reflects the natural topography. The earthworks are now partially levelled. The bank in the S and E averages 4.6m high and follows the contour below the crest of the slope. It defines the upper side of an infilled 5m wide ditch, beyond which is a bank or counterscarp which stands up to 0.6m high. A rubble core is visible where a recent track has cut through the counterscarp. Collectively the overall width is approximately 9m. In the N, the ditch terminates opposite the intersection with the 'cross-ridge' N-W earthworks, with the outer bank continuing for a further 25m. Both the ditch and bank have well-defined terminals. An excavation across a V-shaped ditch by Herman Ramm in 1964, although not accurately located, suggests a possible second earthwork set back from the escarpment. The 'cross-ridge' earthworks are represented by a broad ditch and a presumed bank on the S, which would have defended the gentler slopes of the promontory and in the W the level approach to the promontory. Within Ox Carr Wood, a 120m stretch of the defences survive in relatively good condition, with the average width of the ditch 6m wide and 0.4m deep and the bank approximately 10m wide and 0.2m high on its S side, turning abruptly at the intersection with the contour-following earthwork and running for 16m along the top of the major scarp. A possible counterscarp bank has also been observed. Where destroyed, the remainder of the earthworks have been recorded through magnetometry and on aerial photographs (Bartlett 1982). The interpretation by Oswald and Keenan is that these earthworks were designed to complement the ramparts that follow the contours except at one location where the counterscarp of the contour-following earthwork continues for some distance beyond its intersection with the 'cross-ridge' earthworks. The narrowness of the ditch would have produced a relatively small volume of soil with which to build a dump rampart and is inconsistent with the 10m wide bank leading the investigators to speculate that the construction was a timber box rampart. Possible entrances lie on the level approach at the western end and a second entrance facing NE towards the mouth of the valley of the Cram Beck. No internal features are recorded. Almost half of the site has been lost through quarrying with further areas disturbed by modern forestry operations and landscaping for 19th century estate workers' cottages. However the continuation of the defences in the N and W was confirmed by geophysical survey and partial excavation by the University of York.
