CLAGGAN, a headland and a bay in the barony of Ballinahinch, co. Galway, Connaught. The headland is the termination of the peninsula which separates the bay of Ballinakill from Claggan bay; it looks direct towards Innisboffin, lying at the distance of 2 ¾ miles to the west-north-west; and it bears aloft a landmark called Claggan Tower. The bay is rather more than 1 ¼ miles wide at the entrance; it penetrates the land 2 ¾ miles east-south-eastward, and gradually narrows almost to a point; and it has good shelter, safe anchorage, and alway a sufficient depth of water to float the largest vessels. A quay was built for the promotion of the fisheries; but, in order to afford safe shelter for boats in winter, and subserve the purposes of the herring-fishery in January, it would require a south-easterly extention of 40 feet. The coast around the bay and headland is very wild.
