Local amateur archaeologists Tommy Gallagher and Eddie Harkin have been keeping watch over this spot, where excavations years ago revealed substantial quantities of shells and other midden material; the remnants of countless meals consumed by the area’s ancient inhabitants. These shell middens are essentially prehistoric rubbish heaps, but they’re invaluable to archaeologists as they preserve evidence of diet, seasonal occupation patterns, and daily life from periods when written records didn’t exist.

What makes this site particularly fascinating is what might still lie hidden beneath the surface. Next to the area where the original excavations took place stands a house with a peculiar garden feature: a small, dome-shaped mound. Gallagher and Harkin have noted its unusual profile and suspect it’s no coincidence that this raised area sits so close to where the earlier midden deposits were found. The shape and location strongly suggest that more archaeological material may be preserved under the current ground level, waiting to tell its story.

These coastal middens are common along Ireland’s Atlantic shores, where communities have harvested shellfish for thousands of years. The deposits at Glack or Bohullion likely date back centuries, possibly even millennia, representing generation after generation of people who made their living from the sea. Each layer of shells, fish bones, and other discarded materials forms a timeline of human activity, offering glimpses into how our ancestors adapted to coastal life in this remote corner of Donegal.
