Moated site, Carrowreagh, Co. Roscommon
Sitting on a broad east-west ridge in Carrowreagh, County Roscommon, this intriguing medieval site offers a glimpse into Ireland's defensive past.
Moated site, Carrowreagh, Co. Roscommon
The rectangular area, measuring 38 metres northwest to southeast and nearly 32 metres northeast to southwest, is covered in grass and rushes that have reclaimed what was once a carefully engineered space. The site’s defining features are the fosses, or moats, that surround it on three sides; these water-filled ditches are 3 to 4 metres wide but now only 10 to 20 centimetres deep, their shallow depths suggesting centuries of silting and neglect.
The southwest side tells a different story, where instead of a moat, an earthen bank rises up to defend the enclosure. This bank, roughly 3 metres wide, stands 40 centimetres high on the inside but presents a more formidable 90-centimetre face to anyone approaching from outside. Both internal and external drains run alongside this earthwork, demonstrating the sophisticated water management systems that medieval builders employed to keep their defensive structures intact whilst preventing waterlogging of the enclosed area.
What makes this site particularly fascinating is its proximity to another moated enclosure, located just 80 metres to the east-northeast. These paired defensive sites suggest this ridge was once home to a small but significant settlement, perhaps housing local nobility or serving as an administrative centre during the medieval period. Such moated sites, whilst not uncommon in Ireland, represent the adaptation of Anglo-Norman defensive architecture to the Irish landscape, where natural springs and high water tables made water-filled defences both practical and effective.
