Cacair-Sinchill, and Beallach-in-Mithidheim--as well as numerous churches, the ruins of some being still in existence. The MacClancy clan appear to have sprung from a stock totally distinct from the neighbouring clans of Brefney. Their chief residence was at Rossclogher, but they had another castle--that of Dun Carbery--some ruins of which are still standing close to the village of Tullaghan. This was built in the sixteenth century, and a more commanding site for a fortified house it would have been difficult to select. It was built on the summit of an extensive _Dun_, or fort, which belonged to a period long anterior to the MacClancy rule; and it is a noticeable fact that the name of the original owner of the _Dun Carbery_, son of Niall of the Nine Hostages (fifth century), has continued to the present day as the name by which the castle is known. The Castle of Rossclogher is built on a foundation of heavy stones laid in the bed of the lake, and filled in with smaller stones and earth to above water-level. The sub-structure was circular in form, and the entire was encompassed by a thick wall, probably never more than five feet in height. The walls of the castle are very thick, and composed of freestone, obtained from an adjacent quarry on the mainland. They are cemented together with the usual grouting of lime and coarse gravel, so generally used by the builders of old; the outside walls were coated with thick rough-cast, a feature not generally seen in old structures in the locality. Facing the south shore, which is about one hundred yards distant, are the remains of a bastion pierced for musketry. The water between the castle and the shore is deep, and goes down sheer from the foundation. On the shore, close to the castle, are the remains of military earthworks, evidently constructed by some enemy seeking possession of the castle. On the summit of a hill immediately over this, is a circular enclosure about 220 feet in circumference; it is composed of earth, faced with stone-work. Here the MacClancy-clan folded their flocks and herds, and from this ancient "cattle-booley" a bridle-path led to the mountains above. Portions of this pathway have recently been discovered; it was only two feet in width, and regularly paved with stones enclosed by a kerb.
