A Roman road passes close by, on the south side of the Avon Water, which led to the Roman fort at Loudoun Hill near Darvel. The origins of Strathaven Castle are obscure, but it is believed to have been built around 1350 by the Bairds, on a bend of the Powmillon Burn. Today it is a ruin, with a single tower and sections of wall remaining beside the A71.
