The site of these undated earthwork enclosures has been described as; 'Above the Port, a gully, called the Glion-na-Halaina, comes down Slieau Curn (at SC 342906 on OS 6 inch 1957). Halfway up this little ravine are the remains of two earthworks. The one more strongly defined is a pentagonal enclosure, each side about fifty feet in length, standing on the south bank of the rivulet which divides the gulley. Urns, too, are said to have been uncovered on the site by rabbit trappers.'
