Altar

This feature, listed by Borlase (1897) as a 'dolmen', was later described as a 'chamber tomb' (Killanin and Duignan 1962; 1967). This is an altar at which, it is locally believed, Mass was celebrated during the era of the Penal laws.

This site is associated with early Christian worship, with local tradition holding that Mass was celebrated there during the period of religious persecution in Ireland. No specific saint or cure is linked to the altar, but its use as a place of clandestine Christian ritual reflects broader folklore surrounding sacred and hidden worship sites.
