Monument record 0239802000 - IKM N OF BIERTON CHURCH

APs show a double rectangular enclosure, pits (sunken-featured buildings?) & other features in field where flints & prehistoric/Roman pottery have been found (B2).

Fragmented cropmarks of parts of several rectilinear and curvilinear enclosures possibly part of a settlement of later prehistoric, Roman or early medieval date visible on aerial photographs. On the western edge is the corner of a double ditched rectilinear enclosure with traces of further ditches to the east. Two ring ditches can be seen, one immediatley to the east of the double-ditched feature, the second to the north- which is slightly sub-circular with a possible enntrance ot the east. Patches of possible medieval or post medieval gravel quarrying can be seen across the field. Only part of the remains are visible on a probable gravel island surrounded be deeper soil obscuring the underlying archaeology. Further enclosures and quarrying can be seen in the adjacent field to the east (NRHE record 1596546) (3).

Ditched enclosures and boundary ditches of probable Iron Age and/or Roman date are visible on historic aerial photographs as cropmarks and were mapped as part of the Aylesbury Vale Aerial Investigation and Mapping project (EBC18604). Located in a field about 500 metres NNW of Barnett House and centred at SP 43553 16247, the main features are a double ditched rectilinear enclosure, a curvilinear enclosure and a sub circular enclosure. The double-ditched rectilinear enclosure is incomplete, with only the N, E and part of the S facing sides visible. A ditch up to 1.75 metres wide extends about 31 metres very slightly NNW-SSE. At the NNW end the ditch turns W for a further 20 metres. Parallel to this about 4 metres to the E is the second ditch, up to 1.5 metres wide, that extends slightly NNW-SSE for 46 metres, broken by a 5 metres wide gap. At the NNW end the ditch turns very slightly WSW for a further 13.5 metres. At the SSE end the ditch turns W for 10 metres. About 20 metres to the E of this enclosure is a sub circular ditch up to 1.5 metres wide encloses an internal area about 18 metres in diameter at its widest. Some 82 metres NNW is a subrectangular ditch up to 3 metres wide encloses an area about 19 x 21 metres at its widest points. Extending throughout these features over 200 metres NNW-SSE are patches of (probable) post-medieval extraction (5-6).
