Near the modern village of Hillstreet, a circular fort with a total site footprint of approximately 1ha surrounds the summit and W slopes of hilltop. There are panoramic views from the summit and the site overlooks a number of small lakes and streams to the S. Univallate for the entire circuit, there is no evidence for an entrance gap in the enclosing elements. At the highest point within the interior is a large cairn which probably predates the construction of the fort. The entire monument is under dense woodland which has likely damaged the interior and enclosing elements. First map depiction in first edition Ordnance Survey mapping. More detailed earthwork survey in second edition Ordnance Survey mapping. Site survey by de Valera and O'Nuallain in 1968.
