At Moybella in County Kerry, a ringfort, known in Irish as a rath, once occupied a modest piece of ground beside a small stream to its west. A rath is a roughly circular enclosure, typically defined by an earthen bank and ditch, that served as a farmstead or defended homestead during the early medieval period. Today, nothing of this one can be seen above ground at all.

The enclosure's disappearance has been gradual rather than dramatic. A fieldbank running east to west has cut across the northern side of the site, the kind of incremental agricultural boundary-making that quietly erases earlier land use over generations. The stream to the west, which may once have offered the original occupants a convenient water source or even contributed to the site's natural defences, remains. The earthworks themselves do not. When Caimin Toal compiled the North Kerry Archaeological Survey, published in 1995, the absence of any surface trace was already noted, meaning the site had been effectively lost to the visible landscape before the record was formally made.
