Though no trace of this prehistoric monument appears on the second and third editions of the Ordnance Survey 6-inch maps, its existence speaks to the rich archaeological heritage scattered throughout this northwestern corner of Ireland.

The stone’s disappearance from official records reflects a common fate for many of Ireland’s prehistoric monuments; countless standing stones have been lost to agricultural improvement, road building, and the passage of time. These solitary sentinels, erected during the Bronze Age between 2500 and 500 BCE, served various purposes for ancient communities, from territorial markers and astronomical alignments to commemorative monuments and ritual sites.

This particular site was documented as part of the comprehensive Archaeological Survey of County Donegal, conducted by Brian Lacey and his team in 1983. The survey catalogued field antiquities spanning from the Mesolithic period through to the 17th century, preserving knowledge of monuments that might otherwise be forgotten. While the Glenmaquin Lower standing stone may no longer be visible on the ground, its inclusion in this archaeological record ensures that future generations can appreciate the density and distribution of prehistoric monuments that once dotted the Donegal landscape.
