Ringforts
At the base of Derrymore Island, a low-lying spit of land pushing northward into Tralee Bay, there is a ringfort that exists only in half.
What was once a complete circular enclosure is now bisected by a field fence running east to west, its southern portion long since levelled and the rubble piled against the dividing wall. The effect is oddly surgical: the northern arc survives, the southern has been absorbed into the agricultural landscape, and the two halves tell quite different stories about how Ireland's early medieval past gets worn away.
A rath, as this type of monument is classified, is a ringfort defined by earthen banks rather than stone walls, though this one shows signs of having been reinforced. The surviving northern half retains an earthen bank that was originally faced on both its inner and outer sides with drystone masonry, a technique known as revetment that would have given the enclosure a more substantial, finished appearance. That stonework has largely collapsed now, with only a few short sections still adhering to the bank, nowhere reaching more than two courses in height. The bank itself measures roughly a metre high on the interior side, slightly less on the exterior, and just over three metres wide at its base. A gap of around 2.2 metres on the west-northwest side may be the original entrance. The site's fragmentation is well documented: the first edition of the Ordnance Survey map showed it as an intact circular enclosure, but by the time surveyors returned for the second edition, the field fence had already cut the site in two and the southern bank had been removed. That division has remained essentially unchanged since. The internal diameter of the enclosure, had it survived complete, would have been approximately 22.25 metres, placing it within the typical range for a rural early medieval farmstead of this type. The description of the site was first published in J. Cuppage's 1986 archaeological survey of the Dingle Peninsula, which remains a key reference for monuments across the Corca Dhuibhne region.
