There is nothing to see, no raised bank, no ditch, no scatter of stone. The only clue to its existence is the faint outline that appears in a Google Earth orthoimage captured in November 2018, a ghostly ring in the grass that belongs to a category of archaeological evidence known as a cropmark. Cropmarks form when buried features, ditches, walls, or pits, affect how vegetation grows above them. Filled-in ditches retain more moisture and produce lusher, sometimes darker growth; compacted foundations do the opposite. Seen from above at the right time of year, these differences in the crop or pasture reveal the buried plan of a structure that has otherwise vanished entirely from the surface.

The enclosure at Bohercarron first came to attention not through satellite imagery but through aerial photography carried out as part of the Bruff aerial photographic survey in 1986, catalogued as Bruff 15, AP 5/2131. That survey, focused on south County Limerick, was one of several mid-twentieth and late-twentieth century efforts to systematically photograph the Irish countryside from the air, an approach that transformed understanding of how densely settled the island once was. What the 1986 photographs suggested, the 2018 Google Earth image confirmed more clearly, a circular-shaped cropmark approximately 29 metres in diameter. The site does not appear on Ordnance Survey Ireland historic maps, which means it left no trace in the cartographic record and likely fell out of use or was levelled long before systematic mapping began. A holy well, recorded separately in the Sites and Monuments Record as LI041-071, lies just 20 metres to the north-west, a proximity that may be coincidental or may point to a longer pattern of use in this small corner of the landscape.

The site sits immediately east of a local road that runs along the townland boundary between Bohercarron and Ballylooby. Because there are no surface remains whatsoever, a visit here requires a certain willingness to engage with absence. The field looks like ordinary reclaimed pasture, and without consulting the aerial images compiled by Martin Fitzpatrick and uploaded to the record in August 2021, there is genuinely nothing to orient yourself by. The nearby holy well offers slightly more to observe at ground level. The cropmark itself is best appreciated through the Google Earth orthoimage, where the circular outline is faint but discernible, a reminder that the most complete picture of a place is not always the one available to someone standing in it.
