Occupying a swampy spot, formerly the bed of a lake, are remains of a chapel probably belonging to the monks of Iona. Externally 56 feet in length and 19 feet in width. (Fig. 52.) All the windows are flat-topped and narrow; one in east end, three in south wall, and one in north wall. East wall only is perfect.[98] [Illustration: FIG. 52.--St. Columba, Balivanich. Plan.] Was built in a remote age. The mortar is washed out of the joints. The only door is at north end, with inclined jambs, and so low as to require stooping position on entrance; 4 feet 7 inches high; covered with undressed lintel. Little rectangular windows like portholes. Chancel 14 feet long by 15 feet broad; nave 33½ feet long and 14¼ feet broad. East wall 5 feet thick; east window 2¾ feet by 6 inches wide, greatly splayed at sides inside. Chancel walls--2 feet 2 inches thick--do not bond into nave. Nave window in north wall 14 inches by 7 inches. South wall windows--east one 10 inches square, the other 14 inches by 8 inches. Chancel probably added by Lady Amy end of fourteenth century.[99] 2. EILEAN MOR. A small island lying off the Knapdale coast. “A little way up from the landing-place stands the half-roofless, though in other respects scarcely at all ruinated, shell of ‘Kilvicoharmaig, the Mother Church of Knapdale,’ surrounded by an open and nearly obliterated burying-ground. Its external plan (Fig. 53) is a simple oblong, measuring 37 feet 5 inches in length and 20 feet in width. Internally the building is divided into chancel and nave, the division being a gabled wall open by a semi-circular arch composed of long thin slates. An apartment, which was probably a comparatively modern contrivance, appears to have gone over the nave, as there is a fireplace and chimney in the upper part of the west wall, not bearing marks of antiquity.
