That absence from the historical record is itself telling. Whatever this enclosure once was, it slipped through the documentary net entirely, and only the development of aerial and satellite photography in the twenty-first century brought it back into view.

The site lies roughly 540 metres east of the townland boundary with Ballintaw, in the barony of Smallcounty. It measures approximately 67 metres north to south and 53 metres east to west, and is defined on its western side by a fosse, which is a defensive or boundary ditch, accompanied by an external bank. The remaining sides are marked by a fosse alone, without the bank. The D-shaped plan is a form associated broadly with early medieval enclosures in Ireland, though the site has not been excavated and its precise date or function remains unknown. It does not exist in isolation. A ringfort, another form of enclosed settlement typical of early medieval Ireland, sits around 200 metres to the southeast, and the medieval church and graveyard at Crean lie roughly 390 metres to the west-southwest, suggesting this corner of Limerick was once considerably more active than its quiet pasture now implies. Small relic field boundaries on the northern and southern sides connect the enclosure into the fabric of the surrounding landscape, hinting at a longer agricultural history. The site was formally identified by the Archaeological Survey of Ireland during an aerial photographic survey in 2002, and the record was compiled by Edmond O'Donovan and uploaded in October 2020.

Because the enclosure is a crop or soil mark feature rather than a prominent upstanding earthwork, it is unlikely to announce itself clearly at ground level. Visitors with a serious interest in the site would do best to study the available aerial imagery beforehand, including the OSi orthoimages from 2005 to 2012, the Digital Globe images from 2011 to 2013, and the Google Earth captures from 2016 and 2018, all of which show the D-shape with reasonable clarity. The surrounding land is flat pasture, so the approach is straightforward if access can be arranged, though it is private farmland and permission should be sought. The nearby church and graveyard at Crean offer a more immediately legible point of historical reference for anyone making the trip.
