Situated on a rocky outcrop on Loch Crinan, Duntrune Castle originally dates from the 13th Century with tower house additions in around 1600. Renovated in the late 18th century by the Malcolms of Poltalloch and again in the early 1900s, the family moved out in 1853. The castle is now a Malcolm family home again –having returned in the 1950s after further renovations to the building.
