What we now call Stonehenge stands on Salisbury Plain in Wiltshire at Latitude 51° 11′ North, Grid Reference SU 122 421 on the Ordnance Survey. Its site today is a triangle of 46.9 acres bounded on two sides by roads, the A303 and A344, and on the third by the Larkhill Track. It is owned by the state and administered by English Heritage, a government-funded agency. At this point we come, almost, to the end of the uncontested facts. This greatest of all British stone circles has been, for many centuries, a ruin, but a ruin of what exactly nobody knows.
