The passage tomb at Carrowhubbuck is one such site, a structure whose very form places it within a tradition of prehistoric burial that is among the oldest in the world. Passage tombs, as a type, are defined by a narrow stone-lined corridor leading into a burial chamber, the whole typically covered by a round cairn or mound; they were built by Neolithic communities and are associated across Ireland and western Europe with elaborate funerary ritual and, in some cases, astronomical alignment.

The principal scholarly record for this tomb comes from Seán Ó Nualláin's systematic survey of the megalithic tombs of County Sligo, published in 1989 as part of a multi-volume national inventory. Ó Nualláin's work catalogued the county's extraordinary concentration of prehistoric monuments with methodical care, and Carrowhubbuck appears among them as one fragment of a landscape that was clearly of considerable ceremonial significance to the people who shaped it over five millennia ago. Without the fuller details from the linked survey document, the specifics of this tomb's dimensions, condition, and surviving structural elements are better sought in Ó Nualláin's original volume, which remains the authoritative source for the site.
