Although no one knows for sure, it is likely that these prehistoric ruins are the remains of activity dating from the Neolithic to the Iron Age periods (2500BC to 500AD). What may have been a Neolithic chambered cairn seems to have been made into a house in the Iron Age, with a large walled enclosure attached where sheep or cattle would have been kept. From the parking area at Loch an Dùin, there is a short but boggy walk up hill to Steinacleit, where there are magical views across the Galson Estate and the Atlantic Ocean.
