The structure measures approximately 18 metres east to west and 26 metres north to south, enclosed by what remains of a collapsed stone wall. Sections on the northern and eastern sides still stand up to 0.75 metres high, offering a glimpse of the original defensive structure that once protected this hilltop settlement.

The cashel’s strategic positioning wasn’t accidental; whoever built this ringfort chose their spot wisely. The commanding views would have allowed early warning of approaching visitors or threats along the old route below, whilst the excellent quality of the surrounding land would have supported farming and grazing. A possible outer wall, now largely collapsed, can be traced further down the slope, suggesting this may have been a more complex defensive site than first appears.

This type of ringfort, known locally as a cashel due to its stone construction, represents one of the most common archaeological monuments found across Ireland. Dating typically from the early medieval period, these enclosed farmsteads housed extended families and their livestock, serving as the basic unit of rural settlement for centuries. The Carrick cashel, recorded in the Archaeological Survey of County Donegal in 1983, stands as a tangible link to the everyday lives of Donegal’s early farming communities.
