What is recorded here

Doonalin Coastal Promontory Fort stands on the south shore of Inch Island in County Donegal, Ireland, facing Mill Bay. A natural four-metre drop guards the east while a deep fosse and bank defend the west, creating a narrow coastal stronghold where the sea does the heavy lifting. Road building has scarred the landward defenses, yet the southern edge still holds its shape against the water.

Marked Doonalin on the 2nd and 3rd editions of the OS 6-inch maps. The site consists of a S facing promontory defined on the E by a natural drop c. 4m and on the W by a fosse 5m to 6m deep, a bank and an outer fosse. These features appear to have continued along the N or landward side also but they have been damaged by road building. It is situated on the S shore of Inch Island facing Mill Bay.
