Tallarn Green Moated Site is a medieval moated enclosure situated in Wales on Triassic bedrock of mudstone, siltstone and sandstone. Moated sites of this type typically date from the 12th to 16th centuries and represent the fortified residences of minor landholders and lesser nobility. The water-filled ditch surrounding the site would have served both defensive and practical purposes, controlling access to the dwelling and its associated domestic and agricultural activities. The underlying geology of Triassic rocks would have influenced the drainage characteristics of the moat and the suitability of the location for settlement.
The site's preservation reflects the survival of its distinctive earthwork features—the raised platform and encircling ditch—which remain recognisable despite centuries of agricultural use. Such moated sites are distributed widely across medieval Britain, though their density and form vary considerably by region and period. Tallarn Green's survival as an archaeological monument indicates the robustness of its original construction and the relative stability of its earthworks through later land use.
The site is protected by Cadw, the Welsh heritage monuments service, under reference FL177, ensuring its long-term conservation and accessibility for research and public understanding of medieval settlement patterns in Wales.
