It measures roughly five metres by three, rises to about 1.8 metres in height, and takes a subcircular form, that slightly irregular oval shape common to earthworks that have settled and spread over centuries. What makes it quietly arresting is the traces of stone revetment, a facing of upright or closely set stones used to hold an earthen structure in place, that survive around its perimeter. That detail suggests this was not simply a natural rise in the ground but something deliberately constructed and edged.

The mound sits within the townland of Ceathrú An Teampaill, a name that translates roughly as the quarter of the church, pointing to an ecclesiastical presence in the area at some point in the past, though the mound itself has not been definitively linked to any particular period or function. It was recorded by Tim Robinson in 1980, and Robinson's meticulous work documenting the landscape of the Aran Islands remains one of the most thorough engagements with the human marks left across that limestone terrain. The combination of earth and stone construction, along with the revetment traces, places it within a broad tradition of burial or ceremonial mounding found across Ireland, though without excavation its precise purpose and date remain open questions.
