 In the south-east corner of the walls, the Egyncleugh Tower – whose name means "eagle's ravine" in the Northumbrian dialect – overlooks Queen Margaret's Cove below.A three-storey, square building, across, Egyncleugh Tower was designed to house a castle official, and included a small gateway and drawbridge into the castle, either for the use of the castle constable, or possibly for the local people.There is a postern gate in the eastern wall, added in the 1450s, and a further gateway in the north-eastern corner, which gave access to Castle Point and Gull Crag below.
