The Ness of Onston enclosure
North of the Unstan stalled cairn is an enigmatic earthwork that separates the landward side of the Ness of Onston from the headland.
This arc of two banks and ditches runs across the neck of the point, demarcating an area to the north that is now devoid of visible archaeological remains.
What is known about this feature (and it’s not a lot) has been added to the entry dealing with the Unstan cairn, which has also been expanded and updated.
