Description
Clogwyn Tower is a small tower made of local dolerite rubble, measuring about 1.8 meters in diameter and standing approximately 2.3 meters high. It is topped with large stones arranged to resemble a crenellated parapet. Four iron stirrup hoops are embedded in the masonry, allowing access through the gap in the parapet to the platform at the top. The tower's modest size accentuates the impressive nature of the rocky outcrop on which it stands.
