What appears at first glance to be an unremarkable rock outcrop or large boulder actually contains a curious feature: a small opening measuring about 20 centimetres wide and 20 centimetres high. Peer inside this natural cavity, and you’ll discover another depression of similar depth at its base, creating what archaeologists believe to be a covered bullaun stone.

Bullaun stones are amongst Ireland’s more mysterious archaeological features; shallow, bowl-like depressions carved into rock surfaces that were likely used for grinding grain, herbs, or other materials. Some theories suggest they held religious or ritualistic significance, perhaps containing holy water or being used in early Christian practices. The Meenavoy example is particularly unusual because, unlike most bullauns which are open to the elements, this one appears to be naturally sheltered within the rock face itself.

This modest yet fascinating relic was documented during the comprehensive Archaeological Survey of County Donegal, conducted in 1983 by Brian Lacey and his team of researchers. Their meticulous work catalogued field antiquities across the county, spanning from the Mesolithic Period through to the 17th century, ensuring that even small, easily overlooked features like this covered bullaun were properly recorded for future generations to study and appreciate.
