"Almost entirely destroyed" all that is left is visible on the eroding cliff. It may be very little compared to what was once there but there is surely value in a vertical section that gradually reveals itself without any person having to excavate it ! A watching brief by archaeologists would provide useful results in time. And it goes a long ways along the cliff, over two points of the coast. Either side of the central broch there is 20~30m of settlement, and the broch itself nearly 12m diameter. Apparently there is a slice of a chapel in there too, which I wish I had known at the time. The most obvious structures at this stage in its unveiling are slab-sided floor drains. My photos will tell the story better - all comparitive clarity after Ingshowe and Berstane.
