A cave on the western shore of Loch Caolisport, also in Argyllshire, is associated with the name of the great evangelist of Scotland, St Columba. Like most other cave-chapels, it has the remains of a wall, with a doorway, constructed across the entrance. On a kind of rocky shelf close by the doorway is a rude circular basin, which probably served as the holy-water vessel of the chapel. Against the rock forming the east side of the cave is the altar platform, roughly but solidly built, and still standing—or at least till quite recently—to nearly its full height. On the smooth face of the rock above the centre of the altar platform is a cross carved in relief, of the Latin form, but with its arms and summit slightly expanding towards the extremities. This cross is placed a little to one side of the centre; but more nearly in a central position over the altar there are discernible the almost obliterated outlines of a much older cross which has been incised in the rock. At a little distance from the cave are the ruins of an ancient chapel dedicated to St Columba. It is a small plain edifice about forty feet by twenty-two, with one east window, and the remains of a window in each of the side-walls near the eastern end. The tradition is that St Columba, landing here on his way to Iona, established the chapel in the cave, which was ever afterwards held sacred to his memory, and that the chapel near it was subsequently founded in his honour. The cave was cleared out about two years ago by the proprietor; but no record of what might have been a most interesting scientific investigation appears to have been preserved. It is said that a great many burials were found in the floor of the cave—as many as sixteen or eighteen different skeletons are supposed to have been found—and underneath them the traces of a more ancient occupation of the cavern, probably in pagan times.
