What aerial photography revealed as a spread of ruined field boundaries, covering roughly 130 metres north to south and 140 metres east to west, resolves at ground level into little more than low, sod-covered rises, between one and two metres wide and rarely more than three-quarters of a metre tall, with stones breaking the surface at intervals. The remains are too fragmentary to reconstruct any coherent pattern of ancient fields, and the landscape complicates matters further: natural rock outcrops and areas of what appear to be quarrying blend with the genuine boundary remnants, making it difficult to separate human intention from geology.

The site sits on undulating terrain, with the ground falling away to the south-west into a stream valley and Red Hill rising to the east. It was the aerial photograph, taken as part of a national survey programme and examined when the Record of Monuments and Places was compiled in 1995, that first flagged the site as archaeologically significant. What makes Farranyharpy particularly interesting is the company these field boundaries keep. They skirt or abut a cluster of other monuments in the immediate area: a megalithic structure, a cashel (a type of early medieval stone enclosure, typically circular and used as a defended farmstead), a further enclosure, and two possible hut sites. The field system does not stand alone but appears to have functioned as part of a wider settled landscape, one whose various elements have survived only partially and whose full story remains unresolved.

The boundaries themselves, low and intermittent as they are, become easier to read once you know what you are looking for: the gentle linear swellings in the pasture, the occasional protruding stone, the way the ground seems subtly organised even where no clear wall survives. The surrounding monuments add context, suggesting that people lived and worked across this ridge over a considerable span of time, though no single period has been firmly established for the field system itself.
