The remains form a cashel, a type of early medieval ringfort built from dry-laid stone rather than earthen banks, and what survives here is a roughly circular outline, approximately twenty metres across, its boundary now little more than a low, collapsed ridge of drystone masonry swallowed by vegetation. The overgrowth is heavy enough that the whole structure is effectively obscured, present in the landscape but not easily read by the eye.

Cashels of this kind were typically built during the early medieval period, serving as enclosed farmsteads for a single family or small settlement. The drystone technique, stacking unmortared stone with enough precision to create a stable wall, was well suited to the rocky terrain of Connacht, where field clearance provided ready building material and earthen ramparts were less practical. The Ballysheedy example is modest in scale, and its poor state of preservation makes it difficult to say much more about its original form. No features such as an entrance, internal structures, or souterrains, the underground stone-lined passages sometimes found within cashels, appear to be legible from what remains.
