That transformation, from deliberate geometry to slumped ruin, is part of what makes this caher at Inchee quietly worth attention. A caher is a stone ringfort, a type of enclosed settlement built in early medieval Ireland from dry-laid stone rather than the earthen banks more commonly associated with ringforts elsewhere in the country. This one sits in level pasture on the southern bank of a tributary of the Finglas river, and what remains of it is largely a lesson in how collapse reshapes structure over time.

The enclosure originally measured roughly 18.5 metres north to south and 17.7 metres east to west. Its northern sector survives best, standing 1.7 metres high externally and nearly three metres wide, with a rubble core faced on both sides in drystone masonry, larger slabs forming the outer face. The inner wall-face was terraced, a practical feature that would have allowed movement along the wall's interior at a raised level, though overgrowth and rubble along the southern sector now obscure this entirely. Where the terrace is visible, it sits about 0.8 metres above the interior ground level and is 0.4 metres wide. Set into the inner wall at the north-east is a small lintelled niche, roughly 0.6 metres square and 0.8 metres deep, its purpose uncertain and its interior now filled with loose stone. The original entrance, 1.4 metres wide, faces east, flanked on either side by a pair of upright slabs averaging nearly a metre high. The passage between them is choked with collapsed stone, and the interior of the enclosure itself holds little beyond further rubble, with no visible structural remains surviving above ground.
