The field banks are low, grassed over, and poorly defined, breaking off and resuming without any pattern that makes immediate sense from the ground. They cover an area of roughly 250 metres north to south and 150 metres east to west, which is a considerable extent for something so easily overlooked.

The site came to light through aerial reconnaissance by Markus Casey, the kind of work that routinely reveals what centuries of grass and soil have absorbed. What makes Kiltullagh particularly interesting is that the field system is not simply empty space divided by old walls. Within it sits a cashel, a type of early medieval stone ringfort enclosed by a dry-stone wall, along with a possible house site associated with it. A separate enclosure and a second possible house site lie nearby, suggesting this was once a working settlement of some complexity. To the north of the cashel, a possible trackway survives as two parallel lines of grassed-over stones set roughly 3.5 metres apart and running east to west for about 50 metres, the kind of modest routeway that would have connected a farmstead to its fields or to a neighbouring settlement. Taken together, the components point to a community that organised its land, moved through it along defined paths, and built in stone with enough ambition to leave traces still readable from the air nearly a millennium or more later.
