A passage tomb, for those unfamiliar with the form, consists of a burial chamber reached by a narrow stone-lined corridor, the whole typically covered by a round cairn or earthen mound. What makes Carrowmore collectively so extraordinary is the sheer density of monuments arranged across a relatively compact area, with individual tombs clustered in a pattern that suggests deliberate, long-term ceremonial use of the land over several millennia.

The principal scholarly reference for this monument is Seán Ó Nualláin's survey of the megalithic tombs of County Sligo, published in 1989 as the fifth volume of a national survey series. Ó Nualláin's work brought systematic attention to the Carrowmore complex at a time when many of its tombs were poorly documented, and his volume remains a foundational source for understanding the sequence and character of the monuments there. The tomb is recorded as a National Monument in State care, which places it under the protection of Irish heritage legislation and reflects its recognised archaeological significance.

The central chamber, visible in photographs taken from the east, gives a sense of the scale and construction method typical of Carrowmore's simpler dolmen-style tombs, where large upright boulders support a capstone with little or no surviving passage. The site is accessible as part of the broader Carrowmore complex, where the proximity of so many monuments to one another allows a visitor to read the landscape as something more than a collection of individual stones, and to sense, however faintly, the repeated human choices that shaped it over thousands of years.
