A miniature carpet of tiny moss plants by Cam Loch in North Knapdale.
This small building to the west of St Columba’s Chapel at Kilneuair is described by the authorities as an oratory. Canmore has the following description:
Probably 18th century. A ‘folly’. Square. Rubble, employing ancient carved stones (probably from the chapel); roofless. Very curious small windows formed as acute triangles with slightly curved sides (New built up).
