The Burren and its surrounds are already well known for their concentration of prehistoric monuments, portal tombs, wedge tombs, and court cairns built from the same grey limestone that defines the region's surface, yet individual sites can remain effectively anonymous, known to the archaeological record long before they are known to anyone else.

Mollaneen is a small townland in Clare, a county that contains an unusually dense scattering of megalithic remains, most of them dating to the Neolithic or early Bronze Age, roughly between five thousand and three and a half thousand years ago. The term megalithic simply refers to structures built using large stones, typically without mortar, and in the Irish context these most often served as communal burial monuments or markers in the landscape. Beyond its classification and location, the details of this particular structure, its type, its condition, and its precise form, remain to be fully documented in the public record.
