What is recorded here

Cahernagollum holds a narrow stone chamber, one point three metres high and set east to west inside a broken cairn. Two massive side stones still lean toward each other beneath a thick capstone, forming a box large enough for a person to crouch or lie down. No bones or gifts appeared when quarrymen opened the site, leaving the chamber empty and purpose uncertain. It may have stored something precious, marked a boundary, or waited for a body that never came. The stones remain steady while the meaning drifts like mist over County Mayo.

Found in cairn, during quarrying. Large centrally placed cist (H 1.3m), orientated E-W. Two large side stones remain, one inclined towards the other, and are overlain by a capstone (L 1.2m; Wth 1.5m; T 0.3m). No burials or grave goods were recorded.

Portal dolmen; dates to the Neolithic period (c. 4000–2500 BCE). Its construction reflects early megalithic traditions in Ireland, though its lack of burials suggests it may have had a symbolic or ceremonial function.
