Stane Castle is a tower house built in the fourteenth century and renovated in the eighteenth century. It was built for William Montgomery, son of Hugh Montgomery, first Earl of Eglinton. Repairs were made to the house in 1750 by Alexander, 10th Earl of Eglinton, The four open and four closed pointed windows were constructed for appearance only at this time. An armorial panel stone with the Earl of Eglinton's arms was put up on the west side of the building when this work was undertaken. It is located close to the area of Stanecastle which is on the outskirts of Irvine, North Ayrshire, Scotland (Scottish Gaelic: Inbhir, Siorrachd Àir a Tuath, Alba).
