The site sits on a natural rock platform shaped like the letter D, measuring approximately 20 metres east to west and 9 metres north to south. What makes this location particularly striking is its defensive position; the builders clearly chose this spot for its strategic advantages, with steep drops providing natural protection on the southern side.

The fort’s defences reveal sophisticated construction techniques typical of Irish ringforts. The main enclosure is surrounded by the remnants of a semi-circular stone wall, originally nearly 3 metres wide on the northern side where it’s best preserved. Beyond this primary defence, and sitting 4 metres lower down the slope, runs a secondary line of protection; a concentric bank made of earth and stone, about 3 metres wide, with fosses (defensive ditches) running along both sides. These outer defences naturally fade away on the southern side where the steep terrain made them unnecessary, though two gaps visible in the bank today appear to be later modifications rather than original entrances.

Now surrounded by rough grazing land in Tulach, the cashel represents a type of fortified dwelling that was once common across Ireland, typically dating from the early medieval period. These structures served as defended homesteads for farming families, combining domestic living space with agricultural functions whilst providing security in uncertain times. The substantial nature of the stone walls and multiple defensive rings suggest this was home to a family of some local importance, who could command the resources needed for such extensive construction work.
