Man-made underground passage in Coolykeerane

Coolykeerane hides a man-made underground passage beside its ringfort, probably collapsed into the shallow depression still visible in the ground. Whatever chamber once stood there has surrendered its shape to time, leaving only a dimple for the eye and a suggestion for the imagination. People may have stored, hidden, worshipped or simply passed through beneath that soil. The passage has stopped answering questions, but it still occupies the landscape, waiting to be imagined rather than measured.
