Megalithic Tombs
At Aillemore in County Mayo there stands a megalithic tomb, the kind of ancient stone structure that tends to be filed under "cromlech" in older sources, a term once used loosely for any arrangement of large standing stones or a chambered monument.
The word has largely fallen out of formal archaeological use, replaced by more precise classifications such as portal tomb or court tomb, but it persists in local and historical naming, and its presence here points to a landscape that was shaped, marked, and made meaningful by people living in Ireland thousands of years before any written record.
The principal scholarly reference for this site is the survey conducted by Ruaidhrí de Valera and Seán Ó Nualláin, published in 1964 as the second volume of their Survey of the Megalithic Tombs of Ireland, dedicated to County Mayo. That volume remains a foundational work for understanding the distribution and character of prehistoric monuments across the county, and its documentation of sites like Aillemore helped establish a systematic record of structures that might otherwise have been overlooked or lost to time. Mayo has a remarkable concentration of megalithic remains, a reflection of both its prehistoric settlement and the relative survival of monuments in areas where later intensive development did not obscure or remove them.
