|These strange marks on a stone slab situated close to the chapel at Kilchiaran are man-made. Usually called 'cup and ring' marks, they are quite widespread in Argyll and other, broadly similar marks are found in many other places around the world. They are usually given a Neolithic date, whiich would make them anything up to five thousand years old. Precise dating is however, impossible. Theories as to their purpose are entirely speculative.
