Abstract

Twenty evaluation trenches representing a 3% sample of the site were excavated on a standard north-south by east-west grid. Archaeological features were few, but a sub-rectangular pit was found in the centre of the site in Trench 15 that contained charcoal and small sherds of prehistoric pottery, and a 10m square was opened up around this to determine whether it was an isolated pit or part of a larger group. Four similar pits were found on an east-west alignment, the pits spaced just over 1m apart, and a further pit on the same alignment was found in a trench to the west. A gully running obliquely across the pit alignment was also exposed in Trench 15, plus two pits of different sizes south of the alignment. The only other feature possibly of ancient origin found was an undated larger pit in a trench further to the south-west. Several probable east-west furrows were revealed, one dated by pottery to the post-medieval period, plus a recent field boundary ditch. A north-south ditch crossing the middle of the site contained 19th-20th century finds, and was probably a former field boundary. A large pit of 19th century date was partly exposed at the north edge of the site. Due to the desire to begin construction, evaluation was followed immediately by further archaeological mitigation of the pit alignment and associated features in and around Trench 15. This was extended considerably, as was Trench 14 containing the pit further west. Further 10m squares were dug to the west and east on the projected line of the pit alignment. Fifteen pits of the alignment were exposed in Area 15, and five in Area 14, but no pits were found in the 10m squares further west or east. A further area (Area 21) was therefore stripped closer to Area 14 on the west, and another (Area 22) not far east of Area 15. Area 21 proved to be blank, suggesting that in this direction the alignment had ended, but Area 22 found three further pits on an ENE-WSW alignment. This was different from the alignment in Area 15, so the blank 10m square further east was extended northwards on the new projected alignment, and located another five pits. The pits of the alignment therefore extended for at least 160m across the eastern half of the site. In total 14 of the pits were excavated, and fragments of pottery temperedIn total 14 of the pits were excavated, and fragments of pottery tempered with quartzite were found in five of these, but no other finds except burnt flint and a possible fragment of utilized stone. A sample of charcoal from one of the pits produced a radiocarbon date of 760 – 420 cal BC at 93% confidence. One of the pits in Area 15 was cut by two lengths of curving ditch roughly at right angles with a gap in between, the north-eastern length recut by a shallower gully. The gully, which continued beyond Area 15, contained sandtempered pottery with ferrous inclusions including a pedestal base, suggesting an Iron Age date. South of the alignment one deep and one shallow pit, plus five probable small pits, were found, but none produced any dating evidence.
