A series of rectilinear cropmarks, some running perpendicular to one another, traces the outline of an ancient field system in the townland of Boherygeela, roughly 100 metres east of the boundary with the neighbouring townland of Dunkip. Cropmarks form when buried features such as ditches, walls, or pits affect how overlying vegetation grows, producing tonal differences in grass or crops that show up clearly in aerial photographs, particularly during dry spells. What appears to the walker as ordinary pasture resolves, from above, into the geometry of an organised agricultural landscape.

The site came to light in 1986, not through any dedicated archaeological survey but as a byproduct of infrastructure work. Examination of aerial photographs taken during the planning of the Bórd Gáis Éireann Curraleigh West-Limerick gas pipeline brought the cropmark pattern to attention, catalogued as Map 6, Site 6/21. The field system also shows up on the 1840 edition of the Ordnance Survey six-inch map, where field boundaries and an Ordnance Survey trigonometrical station point are marked, suggesting the landscape divisions were still legible or in use at that date. Within the field system, several enclosures have been identified from aerial photographs, including images taken in October 2002. The relationship between these enclosures and the broader field pattern is not fully understood. Pre-development archaeological testing carried out in 1999 to the south-east of the site by Rose Cleary produced no archaeological remains or finds, which does not rule out the significance of the cropmarks but does leave the dating and origins of the field system an open question.

The site is not accessible as a visitor destination in any formal sense; it sits in private agricultural land, and there is nothing to see from ground level. The most informative way to engage with it is through the aerial and satellite imagery that revealed it in the first place. The field system remains visible as linear cropmarks on Ordnance Survey orthophotographs taken between 2005 and 2012, and on Google Earth images dated to September 2020 and March 2017. Cropmarks of this kind tend to be most pronounced during dry summers, when differential moisture retention over buried features draws a clearer contrast in the vegetation above. For anyone interested in the archaeology of field systems, the record compiled by Fiona Rooney and uploaded to the National Monuments Service in March 2021 provides a useful starting point alongside those satellite images.
