Moated site, Killoughy, Co. Offaly
In a quiet pasture in Killoughy, County Offaly, a low earthen bank traces out an ancient square, marking the footprint of what was once a medieval moated site.
Moated site, Killoughy, Co. Offaly
The earthwork sits atop a natural ridge, its raised platform measuring roughly 22 metres north to south and 24 metres east to west. Though centuries have softened its edges, the defensive bank still rises about 1.25 metres from the surrounding field, whilst inside the enclosure the ground stands 40 centimetres higher than the original surface.
The site’s most intriguing feature is its partial fosse, or defensive ditch, which now survives only along the western side where it cuts about 25 centimetres into the earth. Originally, this water-filled ditch would have completely surrounded the raised platform, creating the ‘moated’ aspect that gives these sites their name. Today, modern field boundaries have cut across the southern and eastern portions of the monument, obscuring much of the original circuit. No trace remains of the entrance that would have once provided access across the defensive works, likely via a wooden bridge or causeway.
This type of earthwork is characteristic of Anglo-Norman settlement patterns in medieval Ireland, typically dating from the 13th to 15th centuries. These moated sites served as fortified farmsteads for colonising families; not quite castles but certainly more defensive than ordinary dwellings. The Ordnance Survey Fair Plan Map, drawn up in the 19th century, marks this particular example simply as ‘Fort’, a common misidentification that reflects how these earthworks were often interpreted before archaeological understanding of their true purpose developed.
