THE CROPMARKS DESCRIBED BELOW, WITH THE EXCEPTION OF THE SQUARE ENCLOSURE WITH ROUNDED CORNERS, ARE NOW RECORDED AS NHER 38903 (THE OVOID RING DITCH) AND NHER 38895 AND 38904 (THE ANOMALIES TO THE WEST).

Cropmarks to W of Calpham Dams Farm.
To the S is an almost square enclosure with rounded corners and a probable entrance to the NE.
To the N is an ovoid (flattened) ring ditch.
To the W are numerous anomalies that may be the fragmentary remains of archaeological features, or may be natural.

The cropmarks described above, with the exception of the square enclosure with rounded corners, are now recorded as NHER 38903 (the ovoid ring ditch) and NHER 38895 and 38904 (the anomalies to the west). This has led to the alteration of the central grid reference of the site from TG 2650 3825 to TG 2654 3818.

The rectangular or square enclosure described above is visible as a cropmark on aerial photographs (S1), centred at TG 2654 3818. It follows approximately the same alignment as field boundaries depicted on historic maps (e.g. S2), and of additional boundaries visible as cropmarks on aerial photographs (NHER 38895). While this pattern of enclosure was current in the later post-medieval period, it may have originated in the Middle Ages. Although the northern side of the enclosure is crossed by one of these boundaries, the fact that the site more-or-less fits into the corner of a field suggests that it too is likely to date to the medieval or post-medieval period.

The enclosure is roughly rectangular in plan and measures up to 49m long and 46m wide. An entrance at its north-east corner appears to be genuine.
