Located in Garravin, about 200 metres south of a townland boundary with Reask, this substantial earthwork sits in improved pasture land that’s been transformed by modern drainage systems and watercourses. Despite its impressive size, the monument never appeared on Ordnance Survey Ireland’s historic maps, only coming to light when archaeologists spotted distinctive cropmarks in aerial photographs taken in August 2000.

The enclosure itself is a sizeable fortification, measuring roughly 70 metres north to south and 77 metres east to west, with a distinctive bivallate design; essentially two concentric defensive ditches that would once have been filled with water. These double moats were typical of Anglo-Norman settlements in medieval Ireland, providing both defence and a statement of power in the landscape. The site shows up particularly well in various aerial surveys conducted between 2000 and 2018, with the outlines of the earthworks creating clear patterns in the grass and crops above.

What makes this site particularly intriguing is the possible field system visible to its north, suggesting this wasn’t just an isolated fortification but part of a larger agricultural complex. The Archaeological Survey of Ireland identified the monument through systematic aerial reconnaissance, demonstrating how modern survey techniques continue to uncover Ireland’s hidden medieval landscape. Today, while the site remains in active farmland with no visible surface features to the casual observer, aerial imagery reveals the complete ground plan of what was once likely a bustling medieval farmstead, complete with its defensive moats and surrounding field systems.
