That much is known. Beyond the name on the map and the fact of its existence as a recorded monument, the details remain, for now, out of public reach. It sits in a county already dense with archaeological remains, from ring forts and wedge tombs to the limestone pavements of the Burren, and yet this particular site has left almost no trace in the accessible record. An enclosure, in the archaeological sense, typically refers to an area defined by a boundary, whether earthen bank, stone wall, or ditch, that served any number of purposes across prehistoric and early medieval Ireland: settlement, ceremony, agriculture, or the enclosing of livestock. Which of these applies here is an open question.

Carrownahooan is a small rural townland, and Clare as a whole contains hundreds of such named enclosures, many of them unexcavated and quietly weathering in farmland or scrub. Without further documentation in the public domain, the site remains a placeholder, a name attached to a point on the landscape, waiting for the kind of attention that might tell us whether it is an overgrown ring fort, a field boundary of medieval origin, or something older still.
