Shanaclogh Castle, Glassdrum, Co. Tipperary South
The castle, whose name translates to ‘the old stone’, was noted by the historian White in 1892 as overlooking the nearby area of Cappagh. Today, what remains of this medieval stronghold tells a story of both endurance and adaptation through the centuries.
The castle’s surviving walls, though poorly preserved, have found new purpose in the modern landscape. The northern wall now serves as a boundary along the main road, whilst the southern wall has been incorporated into the hedge line of a cottage garden built in the early 1900s. This unusual integration of ancient fortification into domestic architecture creates a unique blend of historical periods, where medieval stonework meets early twentieth-century rural Irish life.
The construction techniques visible in the remaining structure reveal the castle’s defensive origins. Built from roughly coursed limestone rubble, the walls feature a distinctive base batter; a sloping foundation designed to deflect projectiles and strengthen the structure against siege warfare. The rounded corners, another defensive feature that eliminated vulnerable angles, can still be observed in the surviving sections, which stand approximately 1.7 metres high and stretch for about 5 metres. These architectural details, documented by Jean Farrelly in August 2011, provide valuable insights into medieval castle building practices in rural Ireland.
