Megalithic tomb, Caoldroim Íochtarach, Co. Donegal
The name references the legendary lovers from Irish mythology who supposedly slept in such stone monuments whilst fleeing across Ireland. Positioned on level ground between the valleys of the Owentilly and Glenna rivers, which both flow northward into Ballyness Bay, this site first appeared on Ordnance Survey maps in the mid-19th century.
When Thomas Fagan documented the monument between 1845 and 1848, he described something far more elaborate than what visitors see today. According to his account, the structure consisted of an eight-foot-long grave chamber enclosed by stone slabs on either side, each standing about 18 inches above ground level. These supported a massive capstone; roughly six feet long, four and a half feet wide, and nine inches thick, its upper surface curiously pocked with small circular holes, each an inch or two across and about half an inch deep. Fagan noted that additional graves once stood nearby, though their stones had already been removed for other construction projects by his time.
Today, the site tells a much diminished story. Two upright stones remain, positioned north to south and standing about 0.7 metres apart, though they’re now partially obscured by a field wall that’s been built directly over them. The eastern stone measures one metre long and stands 0.7 metres high, whilst its western companion is slightly smaller at 0.9 metres long but the same height. A partially buried slab lies just west of these stones, at least 1.3 metres across where visible. Local residents recall more substantial remains existing here until recent decades, but the current fragments bear little resemblance to Fagan’s detailed description, leaving archaeologists uncertain about the monument’s original form and purpose.
