Castle. Island Muller is a small rock-promontory upon the summit of which, approached by means of a grass-grown causeway about 90m in length, there stand the fragmentary remains of a small tower-house of medieval date. The tower, now reduced to its lowermost courses, appears to be constructed of local random-rubble masonry laid in lime mortar. It is oblong on plan and measures 13.3m from E to W by 12.0m transversely; the side walls have a thickness of about 2.8m and the end walls a thickness of 2.6m. An external return in the masonry of the W wall may mark the site of an entrance doorway, while a small relieving-arch near the centre of the S wall (A on RCAHMS plan) probably indicates the position of a latrine-chute outlet. The low turf-grown mound that partly encloses the tower may represent the remains of a rampart-wall of contemporary, or of earlier, date.
It is uncertain whether the causeway is of natural or of artificial origin; it appears to lie above the level reached by the highest tides. At the inner end of the causeway there is a small rectangular platform (X) enclosed on its three landward sides by the remains of a wall of stone or turf; this may have served to shelter small boats hauled up from the shallow little bay situated on the N side of the promontory. The approach track passes the inner end of this platform and skirts the W base of the rock outcrop before turning eastwards to ascend its southern slopes. Immediately before the point at which it begins to ascend, the track passes through what seems to be the remains of a small sub-rectangular building or enclosure (Y) measuring about 10.7m from W to E by 7.6m transversely over all.
Almost nothing is known of the history of this castle, but the simple rectangular plan and massive construction of the tower suggest that it was erected at a comparatively early date within the medieval period. During the 16th century the lands of Ballimenach and Smerby appear to have been held by the MacDonald family, and it is on record that Sir James MacDonald, son of Angus MacDonald of Dunnyveg, imprisoned his father at Smerby in 1597.
