Ringfort (Cashel), Casheltown, Gartan, Co. Donegal
This circular stone enclosure measures approximately 22.5 metres across its interior and would have served as a defended homestead during Ireland’s early medieval period. The structure’s stone walls, originally built to a substantial width of 2.5 to 2.75 metres, have endured centuries of weathering; some sections have collapsed whilst others have been rebuilt or remodelled in more recent times.
The fort’s interior is notably flat, suggesting it once housed wooden structures that have long since disappeared. Just outside the southern wall, archaeologists have identified the remnants of a small, semi-circular stone structure that survives to about half a metre in height, possibly an outbuilding or storage area associated with the main fort. The probable entrance to the enclosure faces east, a common orientation in Irish ringforts that may have held symbolic or practical significance.
Today, the site occupies a patch of grazing and agricultural land, surrounded by the boggy, rocky terrain characteristic of this part of Donegal. This ringfort represents one of thousands scattered across Ireland, each a testament to the dispersed rural settlement patterns that dominated the Irish landscape from roughly 500 to 1200 CE. These fortified farmsteads housed extended families and their livestock, forming the backbone of early Irish society long before the arrival of the Normans.
