This project has produced or identified 52 radiocarbon determinations which are considered
reliable. These are from the Monument itself and associated activity.
Phase 1 - the construction of the main Ditch and Banks, the deposition of `structured deposits' within them, the primary silting of the Ditch, and activity which took place on top of this silting.
Phase 2 - the secondary silting of the main Ditch, the wooden post settings within the Monument, and the Aubrey Holes
