The cashel at Caherskeehaun, a cashel being a ringfort built from drystone rather than earthen banks, measures roughly 31 metres across and was once defined by a substantial enclosing wall. That wall is now largely invisible, obscured by overgrowth, overlain in the south by a later field wall, and heaped about with the accumulated rubble of generations of farmers clearing their land. A large cairn of field-clearance stones has been packed against the outer face of the wall in the northern sector alone. The monument has not so much been demolished as quietly absorbed.

The site has accumulated small mysteries alongside its rubble. An L-shaped foundation line observed in the north-west quadrant of the interior in 1983 may represent an internal division wall or the remains of a house site, the kind of domestic structure that would have stood inside a working ringfort during the early medieval period. More striking is what the landowner found when digging a low earthen ridge to the east of the cashel wall, a feature roughly 11 metres long and 1.5 metres wide. It contained bones and small flagstones, suggesting the ridge may have had a purpose beyond simple field management, though what exactly that purpose was remains unresolved. The field walls that once subdivided this part of the landscape, visible on the Ordnance Survey six-inch map of 1933, have since been removed, leaving the cashel in a slightly different arrangement of land than even recent memory recorded.
