What makes this particular example quietly interesting is not the banks themselves but a rectangular hollow cut into the interior ground, a feature that has attracted two quite different interpretations depending on who is doing the looking.

The fort occupies a modest footprint, roughly 17.5 metres north to south and 27.5 metres east to west, projecting northward from the island. Two banks, set 2.6 metres apart, cut across the neck of the promontory. The outer of the two, standing about 1.5 metres high, is thought to be relatively modern in origin. The inner bank, lower and broader at 0.75 metres high and 4.1 metres wide, and retaining a central gap that may once have served as an entrance, is considered the genuinely ancient element. Inside the enclosed area sits a rectangular depression measuring roughly 4.8 by 3.5 metres and sunk about a metre into the ground. T. J. Westropp, writing in 1915, interpreted this hollow as the remains of a hut site, the kind of simple sunken floor occasionally found within early Irish enclosures. Local knowledge, however, has long held a different view: that the depression was used as a flax-retting pond, a soaking pit where harvested flax stems were submerged in water to loosen the fibres before processing into linen. Both readings are plausible, and neither has been definitively settled. The tension between the archaeologist's instinct and the community's memory is itself a small story about how the past gets read and re-read over time.
