Castell Collen is a Roman fort situated near Llandrindod Wells in Radnorshire, Wales, dating to the late first or early second century AD. The site occupies a defensive position overlooking the River Ithon and represents part of the Roman military infrastructure established during the conquest and consolidation of Wales. The fort's earthworks remain visible as a series of ditches and ramparts, though the site has not been extensively excavated in modern times. It served as a strategic garrison post within the broader network of Roman forts designed to control the indigenous population and secure the mineral-rich regions of central Wales.
