Promontory fort - inland, Croagh (Corkermore Ed), Co. Donegal
Tucked away at the southern tip of a narrow rocky ridge in Croagh, County Donegal, lies the remains of an inland promontory fort that makes clever use of the natural landscape.
Promontory fort - inland, Croagh (Corkermore Ed), Co. Donegal
The site occupies a dramatic position with sheer drops on three sides; to the south, west and east; whilst the more accessible northern approach would have required defensive structures. What survives today is a small, roughly circular earthwork measuring approximately 18 metres from northeast to southwest and 14 metres from west to east, defined by a low but wide earthen bank that encircles a flattish interior area.
The most intriguing feature of this fort is found at its southwestern end, where a narrow depression cuts deep into the ground, running from the outer perimeter towards the centre of the enclosure. This depression leads to a curious circular, rock-cut hollow about 4 metres in diameter, which appears to have been deliberately carved into the bedrock. Around the southern quarter of this hollow, you can still make out the remnants of a tiny earthen bank, suggesting this feature held some particular significance or function for the fort’s inhabitants.
Whilst the exact date and purpose of this fortification remain unclear, its strategic positioning and modest size suggest it may have served as a defended farmstead or small stronghold, taking advantage of the natural defences provided by the rocky promontory. The rock-cut depression at its heart remains something of a mystery; it could have served as a storage pit, a water cistern, or perhaps held some ritual significance to the people who built and occupied this windswept outpost centuries ago.
