Enclosure, Plaster, Co. Donegal
Near the village of Plaster in County Donegal, a small rise in the countryside holds an archaeological secret that's completely invisible to the modern eye.
Enclosure, Plaster, Co. Donegal
Though nothing remains above ground today, this spot once hosted a subcircular enclosure that appeared clearly on the first and second editions of the Ordnance Survey 6-inch maps. The site, positioned on the crest of a gentle hill with commanding views across the surrounding good farmland, has since vanished from the landscape, leaving only cartographic and photographic evidence of its existence.
Aerial photography from the St. Joseph collection reveals fascinating details that ground surveys can no longer detect. The main enclosure appears as a ghostly outline in the photograph, complete with internal divisions that suggest it may have been partitioned for different purposes; perhaps separating livestock, storage areas, or living spaces. Even more intriguing is the presence of a second, slightly smaller subcircular enclosure attached to the north side of the main structure, creating a figure-of-eight arrangement that hints at an expansion or a deliberate dual-purpose design.
These types of enclosed settlements were common throughout Ireland’s archaeological landscape, typically dating from the Early Medieval period through to more recent centuries. While the exact age and function of the Plaster enclosures remain uncertain without excavation, their position on productive agricultural land with good visibility suggests they may have served as farmsteads or small defended homesteads. The site was documented as part of the comprehensive Archaeological Survey of County Donegal in 1983, which catalogued the county’s field antiquities from the Mesolithic period through to the 17th century, ensuring that even these invisible monuments remain part of the historical record.
