Built sometime in the 15th or 16th century, this four-storey fortified residence was once home to the local gentry who needed both comfort and defence in equal measure. The castle’s name derives from the Irish ‘Tiobra Fhachna’, meaning Fachna’s Well, pointing to an ancient water source that likely determined the site’s original settlement.

The tower house follows the typical design of its era, with thick walls narrowing as they rise, murder holes above the entrance, and narrow arrow slits that served as both windows and defensive positions. What makes Tiberaghney particularly interesting is its relatively intact state; visitors can still make out the distinctive features of medieval domestic life, including the remains of garderobes, fireplaces, and the spiral staircase that once connected all floors. The ground floor would have served as storage, whilst the upper levels housed the living quarters, with the top floor reserved for the lord’s private chambers.

Though now roofless and open to the elements, the castle remains an evocative reminder of a time when the Irish countryside was dotted with these small fortified homes. The surrounding landscape has changed dramatically since the castle’s heyday, when it would have overlooked farmland worked by tenants and provided a strategic vantage point over the surrounding countryside. Today, it stands quietly in a field, accessible to those willing to seek it out, offering a tangible connection to Ireland’s complex medieval past without the crowds found at more famous sites.
