Moated site, Knockacorha, Co. Roscommon
Located atop an east-west drumlin ridge in Knockacorha, County Roscommon, this medieval moated site presents a fascinating glimpse into Ireland's defensive structures from centuries past.
Moated site, Knockacorha, Co. Roscommon
The site consists of a square, grass-covered platform measuring 32 metres on each side, surrounded by earthen banks that have weathered considerably over time. These banks, ranging from 3.4 to 4 metres in width, stand between 25 and 50 centimetres high on the interior side, whilst the exterior heights vary more dramatically; from 1 metre on the eastern side to 1.7 metres on the southern edge.
The defensive perimeter is further enhanced by outer moats that encircle the earthen banks, though these too show signs of significant erosion. The moats vary in width from 1.3 metres at the southern end to 3 metres at the northern boundary, with depths ranging from 20 to 40 centimetres. Interestingly, no visible entrance remains, leaving questions about how the site was originally accessed. The monument’s current state reflects centuries of agricultural activity, with a north-northwest to south-southeast field wall cutting directly through the centre of the site.
Additional field boundaries interact with the ancient structure in telling ways; an east-west field bank runs along the outside of the northern moat, whilst a northeast-southwest field bank approaches the eastern moat. These later agricultural features demonstrate how medieval defensive sites have been incorporated into the working landscape over generations, creating a palimpsest where different periods of land use overlap and interweave. Compiled by Michael Moore in September 2010, this site represents one of many such moated settlements that dot the Irish countryside, each telling its own story of medieval life and subsequent agricultural adaptation.
