“ It is situated on a platform of conglomerate rock forming a promontory at the south-west of the entrance to Loch Etive and is surrounded on three sides by the sea. It dates from the 13th century, occupying the site of the earlier stronghold in which was kept the Stone of Destiny prior to its removal to Scone (q.v.) in 843. The castle is a quadrangular structure of great strength, with rounded towers at three of the angles, and has a circumference of about 400 ft. The walls are 60 ft. high and 10 ft. thick, affording a safe promenade, which commands a splendid view. ”
