NHER 36756 (Monument record) - Site of double-ditched boundary and associated features of probable medieval to post medieval date at Crostwight

2 August 1995. NLA air photography (S1).
Cropmarks visible of corner of double-ditched enclosure, with an entrance to the north.
The fact that it appears to meet with a boundary on the map (now removed) may suggest it is of medieval or later date, although it is possible that it is Roman.
Several linear features can be seen, including a square enclosure, in the centre of which is a large subrectangular pit, possibly a sunken floored building feature, or a large pit.

The cropmarks described above (and others) are visible on aerial photographs (S1)-(S3), centred at TG 3340 2936. Two sides of an L-shaped double-ditched boundary are visible; too little is visible to tell whether this was part of an enclosure, as suggested above, although the presence of an entrance (at TG 3338 2933) suggests it may have been. The west end of the boundary lies parallel to a former field boundary, depicted on historic Ordnance Survey maps (e.g. S4) and since removed, suggesting a possible medieval to post medieval date for the feature. Further ditches and a possible enclosure to the north, which share the same broad orientation, are likely to be contemporary features. They include a possible rectangular enclosure at TG 3340 2936. Other ditches, which have a more northwest to southeast orientation, represent a separate phase of activity, possibly of Iron Age/Roman date (NHER 45240). A pit-like feature, also to the north of the double-ditched boundary, has been suggested as the site of a grubenhaus, presumably of Saxon date, but there is little evidence to confirm this hypothesis. The square enclosure surrounding it, described above, has not been mapped, as the linear marks in this area seem more likely to be the product of recent agricultural activity than the presence of buried archaeology.

The small rectangular enclosure measures 13m by 8m. The possible grubenhaus, which is oval in plan, measures 5.5m by 3.5m.
