The
Port Way, a
Roman road towards
Sorviodunum (Old Sarum), followed the Bourne valley and passed close to the present settlements. The
Domesday survey in 1086 recorded 15 households at
Eunestetone (Idmiston), on land held by
Glastonbury Abbey; and eight at
Poertone or
Portone, on land held by
Edward of Salisbury and Wulfric the hunter. Idmiston Manor is a house from c. 1600 with 17th-century interior features and an arched gateway from the same period; both house and gateway are
Grade II* listed. The Old Rectory, opposite the church, also dates from the early 17th century and is also Grade II*. A small grass-runway aerodrome was opened in 1917 on farmland at Boscombe Down in the north of the parish for the
Royal Flying Corps, and continued in use until 1920. The site was reopened and enlarged to form RAF Boscombe Down in 1930, then repurposed in 1939 as an aircraft research and testing station. The first hard runway was built in 1945. Now called
MoD Boscombe Down and extending into
Amesbury and
Allington parishes, its research and testing role continues. == Religious sites ==
