Ringforts
In the north Kerry landscape near Derra, a roughly circular earthwork sits quietly in a field, its dimensions carefully measured and its purpose long since changed.
The enclosing bank still stands about 1.8 metres high on its outer face, though it has settled to around 0.8 metres on the interior side, giving the interior a slightly sunken, sheltered quality that would once have been quite deliberate.
This is a univallate rath, meaning a ringfort enclosed by a single earthen bank rather than the multiple concentric banks found at more elaborate sites. Ringforts of this type were the standard farmstead form in early medieval Ireland, broadly from the sixth to the twelfth century, and thousands survive across the country in varying states of preservation. This one measures roughly 25 metres across on its north to south axis and 27 metres east to west, making it a fairly typical example in terms of scale. Its enclosing bank averages about 5 metres in width at the base, and an outer fosse, a defensive ditch dug to heighten the effective height of the bank, survives in sections, running from the north-west through to the north and round to the south-east, and also appearing to the south-west, though it is not continuous around the full circuit. Where it does survive, the fosse sits about 0.6 metres below the level of the surrounding ground and averages 1.6 metres across. Two gaps in the bank, one to the south at around 4 metres wide and one to the east at around 3 metres, likely mark the original entrance points, though later agricultural activity may have widened or altered them over the centuries. The site was recorded and described as part of the North Kerry Archaeological Survey, published in 1995 by C. Toal.
