A/P'S SHOW A DOUBLE RECTANGULAR ENCLOSURE, PITS (SUNKEN-FEATURED BUILDINGS?) & OTHER FEATURES IN FIELD WHERE FLINTS & PREHISTORIC/ROMAN POTTERY HAVE BEEN FOUND (B2).

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 (3-4).
