Stonehenge Timeline

Three large post holes and a tree hole close to Stonehenge show evidence of probable ritual activity on the site long before the appearance of the monument.

Construction of the causwayed enclosure (a type of large prehistoric earthwork) known as Robin Hood's Ball, 2.8 miles north-west of Stonehenge.

Stonehenge Phase I - earthen henge dug on the site.

Stonehenge Phase II - Digging of the Aubrey Holes, which probably contained wooden posts (or perhaps bluestones). Stonehenge functions as a cremation cemetery.

Phase III at Stonehenge, the refashioning of the simple earth and timber henge into a unique stone monument.

The last phase of construction at Stonehenge, the digging of the Y and Z holes outside the outermost sarsen circle.
