A souterrain, which is a stone-lined tunnel or chamber built into the earth, typically as a place of refuge or storage in early medieval Ireland, once ran beneath this earthwork enclosure. By the time anyone thought to record its existence formally, the structure had already been plundered for building material, and its contents scattered or lost.

The story comes from a 1934 account by Bowman, who noted that when Mr Leahy's farmhouse was constructed around a century before that date, the builders helped themselves to the souterrain's stonework. In the course of that demolition, they turned up old bridle bits and swords. Nobody thought to preserve them, and the objects have been lost since. It is a scenario repeated across the Irish countryside, where prehistoric and early medieval sites were treated as convenient quarries long before the value of their archaeology was widely understood. The ringfort itself, a type of enclosed farmstead typically dating to the early medieval period, survives, but the interior is now heavily overgrown, and no visible trace of the souterrain remains above ground.

The site offers nothing spectacular to the eye, and that is precisely what makes it worth thinking about. What is gone matters as much as what survives. The swords and bridle bits suggest a site of some significance, possibly connected to a person of rank or a household with military associations, but without the objects themselves, that thread cannot be followed any further.
