This irregular boulder, wedged into the earth and exposed for about 1.68 metres in length, has a distinctive wedge shape that tapers to a point at its northeastern end. Standing just over a metre at its highest point, the stone has been aligned northeast to southwest, presenting its broad face to anyone approaching from the south.

What makes this boulder particularly intriguing are the markings etched into its southern face. Multiple narrow grooves score the surface in seemingly random patterns, with no discernible design or organisation to their arrangement. Local tradition holds these mysterious markings to be of ancient origin, though their exact purpose and age remain unknown. The antiquarian D.P. Lacy documented these local beliefs in 1983, noting the community’s conviction that the inscriptions date back to Ireland’s distant past.

The stone’s location near Cill Charthaigh (Kilcar) church places it within a landscape rich in ecclesiastical history. Whether the markings represent ancient Ogham script, medieval graffiti, or something else entirely continues to puzzle those who encounter this enigmatic monument. Its integration into a later field boundary has at least ensured its preservation, allowing this curious piece of Donegal’s archaeological heritage to remain accessible to those walking the old laneway to the church.
