Marked on old Ordnance Survey 6-inch maps as a single-ringed fort, this ancient enclosure now exists more in historical record than physical reality. The site sits in an area of rough pasture, where the rocky terrain would have necessitated stone construction for any defensive structure; a practical choice given the abundance of local building material.

Today, visitors to this windswept hilltop might struggle to identify any definitive traces of the monument that once stood here. Some sections of walling on the northwest portion of the site may represent original fortification, though archaeologists remain cautious about making such claims with certainty. The fort’s strategic position, commanding views northward over Doo Lough, hints at its likely purpose as a defensive stronghold or territorial marker for the community that built it.

This elusive monument forms part of County Donegal’s rich archaeological landscape, documented in the comprehensive Archaeological Survey of County Donegal compiled by Brian Lacey and his team in 1983. The survey catalogues field antiquities from the Mesolithic period through to the 17th century, preserving knowledge of sites like this Croagh fort that might otherwise fade from memory entirely. While the physical structure has largely returned to the earth, its inclusion in these historical records ensures its place in the broader narrative of Irish settlement and fortification.
