Mingary Castle (excluding the boiler room within castle ditch, all interiors and the glazed timber and slate link between the main block and the east range) Kilchoan

Mingary Castle is a medieval castle dating to around the late 13th century, with significant alterations and additions in the late 16th and 17th centuries, further early 18th century additions, and 21st-century reconstruction work. The castle consists of an irregular polygonal curtain wall, incorporating a wall walk and two corbelled turrets situated at the southwest and southeast corners. The walls are constructed from random rubble with distinct horizontal coursing. The enclosure follows the shape of a rocky outcrop above the shoreline, with a rock-cut defensive ditch to the north. There is a seaward entrance through the south curtain, and a landward entrance approached from the north over a causeway that crosses the defensive ditch; remnants of an earlier drawbridge arrangement remain.

Within the enclosure, a three-storey and attic range stands against the north wall. This range is largely of 18th-century construction, adapted from an earlier medieval building. It contains two rooms of unequal size on each floor, accessed via a new timber scale-and-platt staircase located within an existing stairwell. Additional ranges are found against the west and east walls. The west wall range features a single-pitched roof and comprises two storeys, with a single basement chamber at its south end, accessible from the courtyard. This range represents a medieval or early modern structure adapted in the 17th or 18th centuries, although much of the west wall dates from 2014-15 when the castle was brought back into use. The east range is also a single-pitched lean-to structure, appearing to be an 18th-century addition.

The castle was restored between 2013 and 2016, having been a roofless ruin since the mid-19th century. This restoration involved the insertion of a flat-roofed boiler house within the castle ditch, and new roof and floor structures, interior finishes, windows, doors, and services throughout the castle.

Excluded from the listing are: the flat-roofed boiler room within the castle ditch, all internal features, and the glazed timber-and-slate link connecting the main block to the east range, all of which are part of the 2013 conversion. This exclusion is in accordance with Section 1 (4A) of the Planning (Listed Buildings and Conservation Areas) (Scotland) Act 1997.
