Though little remains visible today, this rectangular earthwork once appeared on 19th century Ordnance Survey maps as a distinct raised area measuring roughly 36 by 37 metres. The site sits just 20 metres south of a corn-drying kiln, testament to the agricultural activity that once characterised this waterlogged landscape.

Archaeological investigations between 1997 and 1999, prompted by the construction of the N20/N21 Adare-Annacotty road scheme, revealed fascinating details about this heavily truncated monument. Excavations led by various archaeologists, including Audrey Gahan and Ciara McManus, uncovered portions of a substantial rectangular ditched enclosure dating to medieval times. The ditch itself was an impressive feature, ranging from 2.38 to 3.72 metres wide and reaching depths of up to 1.43 metres. Its inner face showed evidence of stone revetment, whilst the fill contained medieval pottery sherds, animal bones and seashell material; clear signs of domestic occupation.

The excavations revealed that the enclosure likely had an inner bank, evidenced by large quantities of stone within the ditch fill that probably represented collapsed facing material. Whilst no evidence of internal structures or a raised platform survived, this absence is likely due to the limited area excavated rather than their original absence. Earlier activity on the site included a series of gullies and ditches of unknown date, whilst external features such as a charcoal-rich rubbish pit containing burnt stone hint at the daily life of the site’s medieval inhabitants. Today, the monument exists only as a series of slight humps and hollows in the landscape, its former prominence preserved mainly in historical maps and archaeological records.
