Moated site, Cooliska, Co. Limerick
Measuring 25 metres north to south and 40 metres east to west, this earthwork is defined by a scarped edge that drops about a quarter of a metre to an inner fosse, or defensive ditch, with a base width of one metre. Between the inner and outer defensive features sits an earthen bank that rises to 0.6 metres on the interior side and 0.55 metres on the exterior, creating a raised barrier that would have provided additional protection to whatever structures once stood within.
The site’s defensive layout includes an outer fosse running from the southeast to northeast corners, with a base width of 0.8 metres and a depth of 0.25 metres, though time and agricultural activity have altered its original form. A possible original entrance, approximately 4 metres wide, appears to have cut through the western bank, providing access to the enclosed interior. Today, a field drain follows the line of the external fosse from northeast to southeast, whilst the intermediate bank has been incorporated into the modern field boundary system.
The southeastern to southwestern section shows evidence of later agricultural modification, with the external fosse having been re-cut to serve as a field drain. Despite these changes over the centuries, the interior of the site remains level and clear of overgrowth, allowing visitors to appreciate the scale and layout of this medieval earthwork. Such moated sites were typically constructed between the 13th and 14th centuries, often serving as fortified farmsteads or minor manor houses for Anglo-Norman settlers or prosperous Irish families.
