Moated site, Knockalegan, Co. Tipperary South
This roughly rectangular earthwork measures approximately 34 metres from north to south and 32 metres from east to west, enclosed by an earthen scarp that rises 0.7 metres on its exterior side. The scarp itself is quite substantial at 4.8 metres wide, accompanied by a broad, flat-bottomed fosse (or defensive ditch) measuring 1.7 metres across, and a slight external earthen bank that adds another 3 metres to the overall width of the defensive perimeter.
The site shows clear signs of its considerable age, with the fosse now almost completely filled in and barely visible along the northern side, particularly from the northwest to northeast sections. Time and agricultural activity have taken their toll on the external bank as well, which has disappeared entirely along the northern edge where a modern drainage channel now runs east to west along what would have been the bank’s outer base. The northern side of the moated area extends slightly longer than the other sides at 36 metres, creating a subtle asymmetry in the overall rectangular plan.
Despite centuries of weathering and infilling, the interior of the site remains level, dry, and free from overgrowth, making it relatively easy to appreciate the original defensive layout. While the original entrance can no longer be identified amongst the earthworks, the surviving scarps and traces of the fosse still clearly define this medieval enclosure. Such moated sites were typically constructed between the 13th and 14th centuries, serving as fortified homesteads for Anglo-Norman settlers or prosperous Irish families during a period when local defence was a constant concern.
