This grass-covered enclosure, measuring 70 metres east to west and 54 metres north to south, is defined by flat-bottomed moats that once completely surrounded the site. The moats, roughly 9 metres wide at their base and up to a metre deep, are accompanied by outer banks that still stand up to 75 centimetres high in places, though sections have been removed on the western side and along the northern edge.

The site occupies a low-lying position between two ridges that run northwest to southeast, creating a natural hollow in the landscape. Two stone field walls now cross the interior from north to south, but these are later additions; more intriguing are the field banks connected to the original outer bank at the northeast and southeast corners. Historical aerial photographs from 1972 reveal what appears to have been a roadway, now vanished, that once ran about 100 metres northeast from the site towards Oran church, located roughly 500 metres away.

Despite its proximity to the church and its distinctive moated form, the site’s original purpose remains elusive. Archaeological testing carried out in 2004 just 30 metres to the southwest yielded no related artefacts or dating evidence. The moated enclosure has been documented since at least 1911, when it caught the attention of early antiquarians, but whether it served as a medieval manor, a defensive position, or had some other function entirely continues to be a matter of speculation amongst historians studying this part of rural Roscommon.
