These are the remains of a bastle, a defended farmhouse built in the late 16th or early 17th century. It stands in a well-defended position on a rocky crag above the Warks Burn. It is rectangular in shape and has thick stone walls. Only the lower parts of the bastle walls are standing. The original doorway is in the middle of the west wall. A drawing of the bastle made in 1940 shows the western part of the stone vault still standing. The house was inhabited until the mid-19th century. It is a Scheduled Monument protected by law.
