Promontory fort — coastal in Acaill Bheag

Situated in an area of fertile grazing land along the low-lying indented shoreline of the island. The shore is accessible from the site which commands a good view along the sound between Achill and Achillbeg islands. An irregularly shaped W-facing headland measuring 90m long and 27m wide has an isthmus which was fortified by several earthen banks and ditches. The interior is featureless. Crossing the narrow isthmus are two low earthen banks and two flat bottomed ditches. They are both well preserved towards the N, deteriorating to the S. The inner bank averages 0.8m high and 2m wide, while the outer bank stands only 0.4m high and is 1.5m wide. Both are round topped and show no trace of having been faced with stone. The intervening ditch is 2.5m in width and the outermost one averages 2m in width and 0.6m below ground level. A path runs along the southern cliff edge. Besides the path there is no trace of an entrance. The proximity of the site to sea level may explain the poor condition of the remaining features. To the W of this at a distance of 20m within the interior lie the remains of a third earthen bank running across the headland. It is straight and only 0.3m high and 1m wide and may be a later field boundary. Several sheep gaps run through this bank which does not have a corresponding ditch. Outside the fort along the northern edge of the shore 10m from the neck of the headland are the remains of a circular hut (MA065-031002-). It is 4m in diameter and has two narrow gaps in its perimeter wall. This wall only remains as a 1m wide 0.40m high grassed over collapsed bank of stone and earth. Nearby lie the remains of two short lengths of earth and stone bank, and also a pile of beach pebbles and an irregular setting of slabs. The relationship of these features to the fort is unclear. They may be the remains of fishermen's huts as a nearby sheltered cove is easily accessible from this point. The site occupies the headland immediately to the N of a much smaller fort (MA065-032001-) which had been described by Westropp. These descriptions are derived from the MA thesis of Markus Casey 1999 The coastal promontory forts of Ireland.
