The example at Carncreagh in County Clare is one such site, a prehistoric burial structure whose precise arrangement of stones speaks to funerary traditions stretching back thousands of years. Wedge tombs, so called because of the characteristic narrowing and lowering of the burial gallery from front to back, are generally associated with the late Neolithic and early Bronze Age, roughly 2500 to 2000 BC, and Clare has an unusually dense concentration of them across its limestone and shale uplands.

The monument at Carncreagh was documented by Ruaidhrí de Valera and Seán Ó Nualláin in their 1961 volume on the megalithic tombs of County Clare, the first instalment of what became a landmark survey of prehistoric burial monuments across Ireland. De Valera and Ó Nualláin dedicated considerable fieldwork to cataloguing Clare's tombs at a time when many were poorly understood or simply unrecorded, and their survey remains a foundational reference for anyone working on the prehistory of the region. The Carncreagh tomb is part of a broader pattern of such monuments found across the Burren and its surrounding areas, where the exposed karst geology and shallow soils have helped preserve structures that elsewhere might have been swallowed by later agriculture or development.
