Castle-Stalker, an ancient square tower in Lismore and Appin parish, Argyllshire, on a rocky islet in Loch Linnhe, off the mouth of Appin Bay. Built by Duncan Stewart of Appin in the reign of James IV., who used it as a hunting-seat, it was re-roofed and re-floored in 1631, and comprises three stories, rising above a prison vault. Over the entrance-gate is a fine carving of the royal arms; and, save that it is now roofless, it still is tolerably entire.
