This large coastal promontory is situated at 'Port Point' adjacent to 'Portnafrankagh Bay', c. 6km NW of Belmullet Co. Mayo. It is not annotated on any edition of the OS six-inch maps. Noted by Otway in 1845 who records that local folklore says that 'the last inhabitant of Porth Fort was a desperate tyrant, Shane Gill' who was drowned by the local inhabitants due to his cruelty. The promontory forms an irregular headland that projects W from the mainland between 'Portnafrankagh Bay' and 'Doonaderg' inlet, rising gently out of the low-lying neck on the E. At the lowest point of the neck a massive stone wall has been drawn across the headland from NNW to SSE. It is 3m thick, composed of large blocks and has a maximum height of 1.5m. At the southern end a stone-faced bank turns to the SW and continues and though virtually levelled after a short distance, its line is traceable to the shore of Portnafrankagh Bay. The stones in the N section are up to 1.2m long and 0.6m thick (Westropp 1912, 210). Westropp describes one gateway in the middle of the neck, and also mentions a second; stone lintels lay outside both gates. The interior of the promontory extends to about 18ha, and on a low rocky ridge c. 35m from the wall, the foundations of a group of hut-sites and two souterrains can be seen, largely surrounded by an area of cultivation ridges (SH).

This large coastal promontory is situated at 'Port Point' adjacent to 'Portnafrankagh Bay', c. 6km NW of Belmullet Co. Mayo. It is an irregular headland that projects W from the mainland between 'Portnafrankagh Bay' and 'Doonaderg' inlet. It is defended at the lowest point of the neck of the headland by a massive stone wall running N-S for a distance of 88m.

The promontory is not annotated on any edition of the OS six-inch maps. Noted by Otway in 1845, who records that local folklore says that 'the last inhabitant of Porth Fort was a desperate tyrant, Shane Gill' who was drowned by the local inhabitants due to his cruelty. Browne (1895) calls the site 'an earthen d–n, barely traceable'. Visited and surveyed by Westropp in 1912 who recorded defences and internal features.

Inside the promontory, on a low rocky ridge c. 35m behind the wall, are the foundations of a group of hut-sites and a souterrain. From S to N they comprise: a cell with an aumbry; a curved souterrain 6.4m long; a larger circular hut-site 5.4m across; a hut with two cells; 10m further N another souterrain; two huts; a hut-garth with a wall 1.8m thick and two rooms; and beside it a nearly levelled hut, 6.4m overall.
