What survives today is a single section of wall, roughly 11 metres long and rising 6 to 7 metres high, its upper portions cloaked in thick ivy. The castle first appeared on the 1837 Ordnance Survey map as a narrow rectangular building oriented northeast to southwest, sitting within a patchwork of small rectangular fields that once defined this rural landscape.

The castle wall, though weathered and partially collapsed, still dominates the site. A large block of fallen masonry lies to the east, testament to the structure’s gradual decay over centuries. The mound itself holds archaeological interest; its summit features a roughly rectangular enclosure immediately south of the standing wall, suggesting this was once a more substantial fortification. The elevated position would have provided defenders with clear sightlines across the surrounding countryside, a crucial advantage in an era when local conflicts were commonplace.

Recent agricultural activities have somewhat altered the immediate landscape. A stream flowing east to west about 10 metres north of the castle has been drained, with the excavated material forming a low bank along its southern edge. Despite these modern interventions and the presence of a silage pit near the collapsed masonry, the site retains its historical character. First documented in detail during a 1983 survey, Kilfaughny Castle continues to intrigue historians and archaeologists studying the network of tower houses and fortifications that once dotted the Irish midlands.
