This coastal promontory is situated on Achill Beg Island immediately S of Belnaglas Sound. It is also located between the two coastal promontories of Dunnaglas Fort (Atlas No.1753) and Dunnagurragh Fort (Atlas No.1778). It is an irregular headland connected to the island via a narrow neck which is heavily eroded, leaving an approach no more than 4m wide. Access from the ESE is blocked on the WNW end of this neck by three banks set at intervals, which enclose an area of c. 0.38ha. There are no recorded entrances through the banks. Unlike the other promontory forts in the area, the site is not recorded on any edition of the OS six-inch maps, and it is perhaps telling that it was not visited by Thomas Westropp at the beginning of the 20th century, despite his recording the adjacent promontory no more than 30m to the SW; he may not have considered the banks of antiquity. It is currently under pasture.

The coastal promontory can be described as an irregular headland connected to the island via a narrow neck which is heavily eroded, leaving an approach no more than 4m wide at an altitude of 3m OD. The landmass is defended on the W end of this neck by a series of earthworks running in a N/S direction for c. 12m.

The site is not recorded on any edition of the OS six-inch maps and was not noted by Thomas Westropp during the early twentieth century, despite recording the adjacent promontory no more than 30m to the SW. Only one of the banks is clearly visible on satellite imagery, appearing straight and narrow, and Westropp may have considered them to be of relatively recent date.
