What is recorded here
Coolnalong Castle stands as a two-storey fortified ruin on the northern shore of Dunmanus Bay, built probably in the early decades of the 17th century by the MacCarthy Muclaghs. Its U-shaped plan projects arms from either end of the main block, creating a defensive embrace against the sea and the overlooked land beyond. The structure later became a farmbuilding and dwelling for Durrus Court, transforming its martial bones into domestic utility while preserving original fireplaces and gun loops. This shift from castle to home reveals how martial architecture adapts to civilian life, maintaining its shape while surrendering its defensive purpose.
Two-storey house with attic, on ground sloping gently up from N shore of Dunmanus Bay; overlooked from N. Building of U-plan; main block (17.6m NW-SE; 7.8m SW-NE) with arms projecting from NW (6.5m SW-SE; 5.5m NW-SE) and SE (6.3m SW-NE; 5.6m NW-SE) ends of NE wall. All walls stand to full height except SW of which only ground floor stands. Original gables survive atop centre of NE wall, NW and SE ends of main block; at NE ends of both arms. Plain masonry stack atop gable at NE; main SE stack ivy-clad; remaining three stacks are more elaborate with oversailing caps. Machicolations on side walls of projecting arms poorly preserved; tapering masonry corbels with intervening lintels survive. House adapted as farmbuilding and dwelling for nearby Durrus Court; all window and door opes adapted for wooden frames. Inserted elliptical archway in NW wall gaveaccess to lean-to built inside house (some support walling survives); NW arm converted into dwelling with inserted dividing wall from main block. Original fireplace with bread oven at ground floor in SE wall; gun loop in SW wall beside fireplace. House built by MacCarthy Muclaghs, minor sub-sept of MacCarthy Riabhach (O'Donoghue 1986, 58) probably in early decades 17th century.
