Castle Cluggy, which stands on the peninsula on the north side of the Loch of Monzievaird, is undoubtedly very old, but how old no one can tell. A square tower, about 17 feet by 18 feet, with walls five or six feet thick, of tremendous strength, is all that now remains. It is said to have been a seat of the "Red Cumin," the rival of Robert the Bruce for the throne of Scotland, slain at Dumfries before the high altar. The prison is sometimes said to have been on the island in the loch, but really the dungeon must be sought under the foundations of the tower. In the charter giving Ochtertyre to the Murrays, in the year 1467, it is even then described as an "ancient fortalice." The key of the tower was found about fifty years ago on the east side of the building. The old church of Monzievaird, now converted into a mausoleum, was the scene of a dreadful tragedy, characteristic of the spirit of feudal times. The Murrays and the Drummonds were but ill neighbours in the days of James IV. The collision between them in this instance has been ascribed to the levying of tithes, but without historic grounds; and the law of retaliation is even older than that of teinds, and far more widely practised. In a foray which began near Knock Mary the Murrays or their retainers were overpowered and driven westward. They kept up a running fight round the western base of Tomachastel, and an obstinate struggle took place in the hollow between Westerton and the Loch, where many men fell. The Murrays, however, succeeded in reaching the church, where 120 men able to bear arms, with their wives and children, took refuge. They were followed by the Drummonds, reinforced, as some say, by Campbell of Dunstaffhage, and thirsting for vengeance. Even then they might have escaped, had not one of the Murray clan indiscreetly revealed their hiding-place by aiming a successful shot at one of the Drummonds. The Drummonds now summoned them to surrender, but in vain, and then piled wood round the long, low, heather-thatched edifice, and consumed it with its human holocaust. One Murray alone, David by name, escaped, being aided by one of the Drummonds, who was attached to his sister. He in turn was hated and persecuted by his own clan, and forced to escape to Ireland. After some years he returned thence under the effectual protection of the powerful Abbot of Inchaffray, who was a Murray. He was settled on the Abbey lands, and the property which he received still bears the name of Drummond-Ernoch (of Erin).
