Tory contains three lakes, two of them, Lough Ayes and Lough Ahooey of considerable size ; the other is named Lough A-her. The Commissioners of Irish lights erected a light-house here in 1882, which is of great service to mariners, and has greatly diminished the number of shipwrecks, caused by the position of the island in the direct course, vessels entering or departing by the North Channel. It is visible in clear weather at the distance of 17 nautical miles, the lantern standing 122 feet above the level of the sea at high-water.
