This stone ringfort, measuring approximately 18 metres internally from southwest to northeast and 25 metres from northwest to southeast, once enclosed the oval summit of the hill with defensive walls. Today, only scattered stones from the outer face of these walls remain visible, weathered witnesses to centuries of exposure to the elements.

The interior of the cashel presents a level, grass-covered area that would have once bustled with daily life. These stone fortifications, known as cashels, were typically built between the early medieval period and the 17th century, serving as defended homesteads for farming families of some status. The choice of location was strategic; the elevated position provided clear views across the surrounding undulating countryside whilst the natural rocky outcrop offered additional defensive advantages.

The site's proximity to Kinny Lough and its position within relatively fertile agricultural land suggests this was no marginal settlement. The builders selected this spot carefully, balancing defensive needs with access to water and productive farmland. Though much reduced from its original state, the cashel at Cionn An Locha continues to mark the landscape as a place of historical significance, its scattered stones a testament to the communities who once called this hilltop home.
