Stratford-sub-Castle in Wiltshire, England was anciently a separate village and civil parish but since 1954 has been a northern suburb of the city of Salisbury. At approximately 170 ft above sea level, it is dominated to the east by the remains of an Iron Age hillfort within the boundaries of which a Norman castle was built. This now-ruined castle led to the village taking the name Stratford-under-Castle, later changing to Stratford sub Castle. Stratford lies south-west of the abandoned medieval settlement of Old Sarum which was also built within the area of the hill fort. It is approximately twenty one miles from Southampton.
