Description

Several trenches were dug by hand by the contractors within the Ranger Station between 10th and 16th September 2014, during the replacement of French drains. The trenches extended along the east and south sides of a shed, and along part of the east side of the office. These trenches were approximately 600-650mm wide and 550-700mm deep, and were dug to house replacement drains and low retaining brick walls. A narrow connecting trench, approximately 250mm wide and 400mm deep, was dug between the trench on the south side of the shed and the one on the east side of the office. <1> The uppermost surviving Roman deposit (L14) was uncovered only at the southern end of the trench along the east side of the shed. It was exposed over the southern half a metre or so of the trench and consisted of a brownish-yellow clayey layer, which lay approximately 550mm below the modern ground level. This layer remained unexcavated, but was perhaps derived from the demolished daub walls of a Roman building. Several small fragments of Roman brick/tile were observed in the spoil from this area, although these probably came from the overlying deposit (L12). The Roman layer L14 was sealed by dark greyish-brown post-Roman topsoil or ‘dark earth’ (L12), which at the south-east corner of the shed was approximately 400-450 mm thick. The ‘dark earth’ (L12) was observed in most of the trenches in the Ranger Station, although it was often truncated as a result of later activity. Much of the ‘dark earth’ (L12) probably accumulated in a shallow post-Roman ditch, which extended from south to north under the western part of the Ranger Station. This ditch was located immediately to the south of the Ranger Station in 1983-4 (CAR 6, 372). Further south, in the sand play area, the thick deposits of post-Roman topsoil or ‘dark earth’ that were uncovered in 2014 probably also accumulated as backfill in the ditch (F3). The ‘dark earth’ (L12) excavated on the east side of the shed at the Ranger Station probably lay near the eastern edge of the ditch. Further west, the bottom of L12 was not reached, but in this area L12 was presumably slightly thicker, where it lay nearer the middle of the ditch. Two fragments of human bone were found at the south end of the trench along the east side of the office. They lay at a depth of approximately 400 mm below the modern ground level. The fragments consisted of the distal end of an adult femur (168 g) and the head of a femur (31.5 g). After being identified and photographed, the bone fragments were reburied in the south-west corner of the trench. The bone fragments appeared to lie in post-Roman topsoil or ‘dark earth’ (L12), although they were not observed in situ and there was modern disturbance in the area they came from. No grave cut and no further fragments of human bone were visible in the sides of the trench. It could not be confirmed therefore whether or not the bone fragments were part of an articulated skeleton. There does not appear to be any previous record of human remains found in this part of the Castle Park. Burials have been discovered to the south of the Castle (Drury 1983, 405-7; CAT Report 521, 10). These were probably of prisoners housed in the keep, perhaps in the late 16th or 17th century. Over most of the trenches at the Ranger Station, the ‘dark earth’ (L12) was sealed by a layer of modern topsoil (L11), up to 150mm thick. This had more inclusions, such as small fragments of mortar and brick/tile, than L12. In places, the modern topsoil L11 was sealed by the existing yard surface (L13). This consisted of tarmac, approximately 50mm thick, resting on make-up layers of chippings, gravel and concrete, 70-100mm thick. Several modern services and service trenches were encountered in the trenches. Among these were redundant French drains, including that observed by CAT in 2009 (CAT Report 516). Near the south end of the trench along the east side of the office, a cable appeared to have been laid in a shallow east-west brick-lined gully. A small quantity of finds was noted in the spoil from the trenches. These probably came mainly from L11 and L12, and included modern potsherds, and fragments of modern brick and peg-tile. They were not retained, although further details are available in the site archive.
