Dalmellington is an ancient settlement of indeterminate origin. It is probable that the area was first occupied some 6,000 years ago, when Man moved inland from the West Coast along the rivers.
It was certainly occupied by the Neolithic Period, as cairns and a few scraps of tools from this period have been found. In recent years traces of early human activity have been found around Loch Doon. There may have been crannogs (timber lake dwellings) at Bogton Loch and Loch Doon.
In the medieval period Dalmellington was part of Kyle Stewart and under the rule of a series of Norman lords, invited to Scotland by the king to assist in subduing the country. On behalf of the king they collected taxes and administered justice. It was during this period that “The Dalmellington Motte” was constructed.
