Roughly circular and measuring about five metres across and less than a metre high, it is the kind of feature that could easily be dismissed as a natural rise in the ground, except that it almost certainly is not.

When Mac Domhnaill recorded it in 1933, the classification was plain and unambiguous: an artificial mound. That designation matters. Artificial mounds of this type are found across Ireland in a variety of contexts, from burial mounds of prehistoric date to later medieval features associated with ecclesiastical or territorial boundaries. The name of the townland, Ceathrú An Teampaill, translates roughly as "the quarter of the church," suggesting a long-standing connection between this small patch of Galway landscape and religious land use. The proximity to Teampall Mhuire, a church site, places the mound within that layered ecclesiastical geography that is so characteristic of the west of Ireland, where early Christian foundations accumulated associated structures, enclosures, and earthworks over many centuries. What purpose this particular mound served, whether ritual, funerary, or something else entirely, remains unresolved.
