Old Sarum, in Wiltshire, South West England, is the ruined and deserted site of the earliest settlement of Salisbury. Situated on a hill about two miles north of modern Salisbury near the A345 road, the settlement appears in some of the earliest records in the country. It is an English Heritage property and is open to the public. The great stone circles of Stonehenge and Avebury were erected nearby and indications of prehistoric settlement have been discovered from as early as 3000 BC. An Iron Age hillfort was erected around 400 BC, controlling the intersection of two trade paths and the Hampshire Avon.
