This earthfast stone, measuring 1.55 metres by 1.05 metres and standing 0.55 metres high, bears the distinctive cup marks that characterise much of Ireland’s ancient rock art. The most striking feature is a central cup mark, 7 centimetres across and 2 centimetres deep, surrounded by an unusual double-lined C-shaped ring that spans 26 centimetres in diameter.

The boulder at Meendoran showcases several other decorative elements beyond its prominent central design. Three smaller cup marks, each partially enclosed by rings, are scattered across the stone’s surface. Upon closer inspection, at least two additional possible cup marks can be spotted, though these lack the enclosing rings that define their companions. This combination of ringed and unringed cup marks is typical of Bronze Age rock art found throughout County Donegal and the wider Atlantic fringe of Europe.

Rock art sites like this one offer tangible connections to Ireland’s prehistoric past, though their exact purpose remains enigmatic. Were they territorial markers, ceremonial sites, or perhaps astronomical calendars? The positioning near Lough Fad might have held significance for the people who created these marks thousands of years ago. Today, this decorated boulder stands as a quiet testament to the artistic expression of Ireland’s early inhabitants, its weathered surface still clearly displaying the careful work of ancient hands.
