Cart-based magnetometer survey The survey identified one substantial archaeological site, comprising a square enclosure with a large annex and some possible house platforms, perhaps dating from the late prehistoric or Roman period. This lay towards the centre of the pipeline route, close to East Luddon. Elsewhere there were various doubtful or minor remains, mostly comprising ditches of indeterminate date. Other recorded features included historic field boundaries and a pair of 19th-century quarry pits.
