Ringfort (Rath), Doon Glebe, Co. Donegal
On the southern slopes of Glendoon Hill in County Donegal sits the remains of what appears to be a destroyed ringfort, a circular defensive settlement typical of early medieval Ireland.
Ringfort (Rath), Doon Glebe, Co. Donegal
The site consists of an almost perfectly round platform measuring approximately 55 metres in diameter, enclosed by a low earthen bank and surrounded entirely by a water-filled ditch. Numerous stones are visible both within the ditch and along the platform’s edges, suggesting the original structure may have incorporated stone elements alongside the earthworks. Interestingly, the southern side shows possible evidence of a double or stepped bank within the ditch, which could indicate multiple phases of construction or a more complex defensive design than initially apparent.
Near the centre of the platform lies a partially buried oval stone, measuring 1.8 metres by 1.15 metres and oriented along a north-south axis. This recumbent stone rises just 10 to 20 centimetres above ground level and may have held ritual or practical significance for the fort’s inhabitants. Local records from the National Museum of Ireland mention a bullaun stone, a rounded granite block with a deliberately cut depression often used for grinding or ritual purposes, located at the southwest of the ringfort, though recent surveys haven’t been able to confirm its presence.
The ringfort’s positioning offers commanding views across the surrounding landscape, a strategic advantage that would have been crucial for both defence and monitoring agricultural lands. Despite the somewhat waterlogged conditions today, the land quality remains good, suggesting this would have been an attractive settlement location in ancient times. This site forms part of Donegal’s rich archaeological heritage, documented in the comprehensive Archaeological Survey of County Donegal, which catalogues field antiquities from the Mesolithic period through to the 17th century.
