A cashel is a dry-stone enclosure, typically circular or oval, used in early medieval Ireland to define a settlement or farmstead, and this one at Gowlane sits in a position that feels quietly deliberate, oriented towards the bay rather than sheltered from it.

Within the cashel, one of the huts, the third in the recorded sequence, sits immediately north-west of its neighbour and may have been physically joined to it. It is circular, with an internal diameter of four metres, and enough of the inner wall face survives to trace most of its circumference. At its tallest, the inner wall still stands to 1.3 metres, though a gap of roughly 2.5 metres interrupts it on the northern side and no outer facing remains visible. These details come from J. Cuppage's 1986 archaeological survey of the Corca Dhuibhne, the Dingle Peninsula, which catalogued the dense concentration of early remains across this part of Kerry. That survey remains one of the more thorough regional inventories of its kind in Ireland, and Gowlane is one entry among hundreds that together suggest the peninsula was far more densely settled in the early medieval period than its current quiet landscape implies.
