Trebersed Moated Site is a medieval moated site located in Wales and protected by Cadw as a scheduled monument under reference CM249. The site sits on bedrock composed of Arenig Rocks, formed during the Arenigian period and consisting of mudstone, siltstone and sandstone. This solid geological foundation provided a stable base for the medieval structures that once occupied the location.
Moated sites of this type were typical of medieval settlement patterns across Britain, particularly from the twelfth century onwards. The water-filled ditch surrounding the central platform served both defensive and practical purposes, offering protection whilst also facilitating drainage and potentially supporting fishponds or water supply. The specific bedrock composition at Trebersed would have influenced both the excavation of the moat and the stability of any structures built within the enclosed area.
Today the site remains an important archaeological record of medieval domestic and manorial organisation in Wales. The preservation of the moated earthworks allows study of settlement hierarchy, land use and social structure during the medieval period. The site's protection under Cadw ensures that this valuable heritage asset is maintained for future research and public understanding of Wales's medieval landscape.
