The one at Ticooly in County Galway is a rather different case. What remains is fragmentary, a partial arc of two banks with a fosse between them, the fosse being a shallow ditch dug between the banks as part of the original defensive arrangement, surviving only from the south, around through the west, and up to the north-north-east. Beyond that arc, nothing is visible at ground level.

The reason for this near-disappearance is straightforward: farm buildings were constructed across part of the site at some point, effectively erasing whatever earthworks once completed the circle. What can still be traced belongs to a circular rath roughly 41.5 metres in diameter. A rath is the most common type of Early Medieval settlement enclosure in Ireland, typically a circular area defined by one or more earthen banks, used as a farmstead or the residence of a local family of some standing, dating broadly from the sixth to the twelfth centuries. The Ticooly example, with its double-bank arrangement and intervening fosse, would once have been a reasonably substantial structure of that kind, set in level grassland that offered little natural defence of its own, making the earthworks all the more necessary.
