The site, surrounded by damp marshland to the west and northwest, offers sweeping views across the countryside. What remains today is a circular heap of stones about 10 metres across and 4 metres high, with only a small section of the northeast corner still standing; including part of a spiral stairwell that reaches just 1.8 metres in height.

This tower house likely dates from after 1574, when it served the O’Loughlin family who controlled this part of County Clare. By 1617, Owney O’Loughlin held Fahee alongside several other castles in the region, including Glencolumbkille and Muckinish. The castle’s fortunes changed dramatically following O’Loughlin’s death, passing first to his cousins Margaret MacDermot and Mary O’Brien, then being confiscated after the 1641 rebellion and granted to John Drew and Lady Blake. The last recorded occupants were Loughlin O’Hehir and Geoffrey Blake in 1659, after which the castle fell into ruin.

Local tradition, recorded in the Ordnance Survey Letters of 1839, suggests this wasn’t a typical castle but rather served as a garrison house with some distinctive military purpose. By the time those letters were written, the structure was already described as ‘nearly crumbled to a heap of rubbish’. The site appears on historical maps as a hachured mound, and Robinson’s 1977 map specifically labels it as ‘Garrison castle’, supporting the oral history that this fortification served a more utilitarian military role than the grander tower houses of the region.
