Forden Gaer is a Roman auxiliary fort located near Welshpool in Powys, Wales, dating to the first and second centuries AD. The site occupies a strategic position in the Severn Valley and was established as part of Rome's military infrastructure for the conquest and control of mid-Wales. The fort's defensive earthworks, comprising multiple ditches and ramparts, remain visible as substantial archaeological features in the landscape.
