Treffgarne Gorge Defended Enclosure is a prehistoric defensive structure located in Pembrokeshire, Wales. The site consists of a fortified enclosure positioned within the dramatic natural setting of Treffgarne Gorge, which provided both defensive advantage and strategic control of the local landscape. Dating to the Iron Age, the enclosure demonstrates the characteristic defensive architecture of its period, with earthwork defences adapted to the topography of the gorge. The site's location within a narrow gorge suggests its builders exploited natural features to strengthen the position against potential attacks, making efficient use of the surrounding terrain as part of the overall defensive strategy.
