The remains are not located in the modern village of Lonmay which is approximately 6 km to the south-west.
It was described by W. Douglas Simpson as one of the nine castles of the Knuckle, referring to the rocky headland of North-East Aberdeenshire.
[4] It has long ceased to be in existence and there are very few remains to be found, all of which are buried under constantly shifting sand dunes that have over time engulfed the site.
[5] The castle provided protection to the north shore of the estuary[6] that used to flow into Strathbeg Bay, before it closed off forming Loch Strathbeg around 1720.
The remains are found "in the Links".. "near the sea"[7] however "all the stones have been carried off, and employed in building farm-houses"[7] and so "except the name, all tradition respecting this building is lost".
