Known as Cathair Bheag na Máirtíneach, a cashel or early stone-walled enclosure, it once contained five corbelled huts; the technique of corbelling involves layering stones inward until they meet at the top, creating a domed roof without mortar. Today, almost nothing of that original settlement is legible as such. What remains has been quietly repurposed, amended, and partially dismantled across the centuries until the boundary between ancient structure and modern intervention has become genuinely difficult to read.

When the antiquarian John Windele recorded the site in 1848, he counted five huts within the enclosure, though only three appeared on the Ordnance Survey maps. By 1899, the archaeologist R.A.S. Macalister found substantial remains of just one hut, with faint traces of the others. That surviving structure, a clochaun or dry-stone corbelled hut, has since been modified into a sheep-fold. Its eastern half is largely destroyed, replaced by a straight modern wall. Internally it now measures 3.5 metres north to south and 2.3 metres east to west, though it was probably originally around 4.5 metres in diameter. The western wall may be original, but has been heightened; the outer face, rising 1.3 metres above a basal mound that could itself represent the remnant of an earlier wall, may have been entirely rebuilt at some point. A narrow entrance faces south-east, and a small lintelled recess in the opposite wall, measuring roughly 32 by 21 centimetres and 40 centimetres deep, still survives, though a second recess recorded by Macalister has since disappeared. A short external wall beside the entrance is likely a later addition, positioned to guide sheep inward. To the east of the main hut, field clearance debris now obscures what Macalister identified as traces of a second clochaun, though the connecting passage between the two structures remains just discernible beneath the surface clutter.
