On the shore of Kilnaughton Bay near Port Ellen (at NR 3476 4550) is this tiny ruined building, which looks to be a small chapel, but Martin can find no mention of it in the sources at his disposal. A comment here suggests that it might have been a changing hut (for sea bathing) for a nearby house, and here as a folly. © Martin Briscoe.
