Located 140 metres north of the Crean townland boundary, this rectangular earthwork measures approximately 27 metres north to south and 18 metres east to west. The site first caught researchers’ attention during aerial surveys conducted before the construction of the Bórd Gáis Éireann Curraleigh West to Limerick gas pipeline, though it had managed to escape the notice of Ordnance Survey Ireland’s historic mapmakers entirely.

The monument appears as a distinctive cropmark on various aerial photographs taken between 2005 and 2020, with a field boundary cutting through its eastern side in a northeast to southeast direction. These same images reveal something equally intriguing; the remains of an extensive field system of unknown age surrounding the moated site, suggesting this area has a long history of agricultural use that may stretch back centuries.

Moated sites like this one were typically constructed during the Anglo-Norman period in Ireland, roughly between the 12th and 14th centuries. They consisted of a rectangular platform surrounded by a water-filled ditch, often supporting a timber hall or tower house where minor lords or prosperous farmers would have lived. The fact that this particular example only shows up as cropmarks rather than visible earthworks indicates that centuries of farming have levelled the original banks and ditches, leaving only subtle differences in soil composition that affect plant growth and reveal the site’s footprint from above.
