Whilst local tradition speaks of a standing stone somewhere in these fields, the first edition of the Ordnance Survey 6-inch map shows no trace of such a monument. This phantom megalith represents one of archaeology’s more intriguing puzzles; a site known through memory and folklore, yet mysteriously absent from the detailed Victorian cartographic records that usually captured even the smallest field boundaries and ruins.

The documentation of this elusive stone comes from the comprehensive Archaeological Survey of County Donegal, compiled in 1983 by Brian Lacey and his team of researchers. This ambitious project catalogued the county’s field antiquities spanning from the Mesolithic period right through to the 17th century, creating an invaluable record of Donegal’s archaeological heritage. The survey notes the standing stone’s reported location amongst the gentle, undulating farmland that characterises this part of the county, though whether the stone still exists, was removed, or perhaps was misidentified in local tradition remains unclear.

Standing stones, or galláin as they’re known in Irish, are amongst Ireland’s most enigmatic prehistoric monuments. Dating primarily from the Bronze Age, these solitary sentinels dot the Irish landscape, their original purpose still debated by archaeologists. Some may have served as territorial markers, others as memorial stones, and many likely held ritual significance we can only guess at today. The Tullydonnell Lower stone, whether lost, hidden, or existing only in collective memory, joins thousands of similar monuments across Ireland that connect our modern landscape to its ancient past.
