Castle, Clonyhurk, Co. Offaly
Standing on flat ground with commanding views across the Offaly countryside, the ruins of Clonyhurk Castle tell a story of medieval defensive architecture, though time hasn't been particularly kind to this once formidable structure.
Castle, Clonyhurk, Co. Offaly
The tower house, which originally stood three storeys tall, now survives as a two storey remnant; its square plan measuring 8.5 metres north to south and 9.5 metres east to west. Built from uncoursed limestone rubble with walls 1.5 metres thick, the castle shows interesting construction details including evidence of wickerwork centring used to support the arches during building, a common medieval technique that left its mark in the stonework.
The defensive and domestic features of the castle reveal how its inhabitants once lived. The ground floor has a window set into a widely splayed embrasure in the north wall, whilst the first floor boasts flat headed windows similarly positioned to maximise light whilst maintaining security. Perhaps most intriguing is the angle loop in the northwest corner at first floor level; this narrow opening sits in an embrasure less than half a metre from the north window, though puzzlingly, it’s too narrow to have served either defensive or domestic purposes, leaving its exact function a mystery. The castle’s sanitation arrangements are evident in the large segmental arched garderobe chute on the north wall’s external face, ingeniously sloped to carry waste away from the building’s base, though the garderobe chamber itself was located on the now destroyed second floor.
Much of the eastern wall has been lost to time, taking with it any evidence of the original entrance and stairs, whilst a medieval church stands nearby to the north, suggesting this was once an important local settlement. The interior floors were supported by wooden beams, now long vanished, and to the west of the tower, possible wall footings hint at an original bawn wall that would have enclosed and protected the castle grounds. These tantalising fragments help us piece together what was once a fully functioning medieval stronghold, even as nature and centuries of neglect continue their slow reclamation of the site.
