0.75 miles west and a walk on surprisingly non boggy ground is the dun, Loch Nan Struban. In the mist and rain it's easy to think every stone is a circle, I wasn't far wrong as there are lots of medieval enclosures in the area.
I approached from Cringraval, east, with the rain lashing down. The new water proofs getting a good testing.
The dun, or hut circle on an island, is surrounded by a fallen wall with a causeway heading south from site. I found the start of the causeway, but no crossing over today to the 11 meter wide island.
