These are tau crosses, named for the Greek letter T they resemble, with no upward arm above the crossbar. The shape has deep roots in early Christian and pre-Christian symbolism, and finding examples here, roughly worked from local stone and set among a field of unnamed headstones and notched markers, gives the site a quality that is quietly disorienting.

A graveyard survey conducted by Laurence Dunne in 2010 documented three of these tau cross-slabs at Kildrum, and noted their close resemblance to examples found at nearby sites including Raheenyhooig and Kilmalkedar. That shared character across several Dingle Peninsula locations suggests a localised tradition, and the crosses are considered possibly Early Medieval in date. The graveyard itself sits at around fifty metres above sea level on the lower slopes of Leathaoibh, with views south towards Dingle Harbour and northeast towards Mount Brandon. The oval enclosure visible on the first edition Ordnance Survey map of 1841 hints at the antiquity of the site, as does the density and arrangement of the grave markers, which likely trace the footprint of a medieval church that no longer survives in any visible form above ground. Around three hundred small headstones, notched markers, and cross-slabs are scattered across the interior, most of them unnamed, the patterns of their distribution carrying the ghost of an earlier, vanished structure.
