Overview

History & significance

Gelligaer Roman Site is a Roman fort located in the parish of Gelligaer in Glamorgan, Wales, dating to the late first and early second centuries AD. The site comprises the remains of a auxiliary fort, likely built during the late Flavian or early Trajanic period, positioned to control the upland regions of south Wales and facilitate Roman penetration into the interior. The fort's layout follows the characteristic playing-card plan of Roman military architecture, with defensive ditches and ramparts still visible in the landscape. Archaeological investigation has recovered evidence of occupation and military activity spanning the first and second centuries, making it a significant example of Roman military infrastructure in Wales and an important monument in understanding Roman frontier strategy in this region.
