Site of Oghil Castle, Oghil Beg, Co. Galway
On a gentle rise in the pastureland of Oghil Beg, County Galway, the remnants of what was once a castle form a modest rectangular earthwork.
Site of Oghil Castle, Oghil Beg, Co. Galway
Measuring 25 metres east to west and 13.4 metres north to south, this grassed-over platform slopes slightly from west to east and rises no more than a metre above the surrounding fields. A low bank of earth and stone runs north to south through the earthwork, just west of its centre, whilst another stony bank traces what might have been the original foundation lines along the western and northern edges. Though much of what you’ll see today is field clearance stone, four large limestone blocks remain embedded in depressions across the site; likely the last surviving fragments of the castle’s original masonry.
The eastern face of the earthwork has worn away considerably over time, and several hawthorn trees have taken root amongst the ruins. Archaeological evidence suggests this may have been a tower house, a type of fortified residence common in medieval Ireland. The castle’s strategic position on raised ground would have offered its inhabitants clear views across the surrounding countryside, an essential defensive advantage in uncertain times.
Adding to the site’s historical significance, the remains of a nunnery once stood just 25 metres to the southwest. This proximity hints at a broader medieval settlement in the area, where religious and secular power centres often existed side by side. Today, whilst the castle exists only as subtle undulations in the landscape, it serves as a quiet reminder of the complex tapestry of medieval life that once flourished in rural Galway.
