Roman Supply Depot, Llansantffraid ym Mechain is a Roman enclosure situated in the parish of Llansantffraid ym Mechain in Wales. The site occupies ground underlain by Caradoc Rocks, a formation of mudstone, siltstone and sandstone that would have presented both practical challenges and opportunities for Roman engineers establishing a supply base in this inland location during the occupation of Britain.
The enclosure follows the characteristic rectilinear plan typical of Roman military installations, with defensive ditching and ramparts designed to protect stores and personnel. Supply depots of this type served crucial logistical functions, holding provisions, equipment and materials for garrisons and military operations across the frontier regions of Roman Wales and the western provinces.
The monument is protected by Cadw, the Welsh Historic Monuments service, under reference MG216, ensuring preservation of this significant evidence of Roman administrative and military infrastructure. The site's survival as an archaeological feature preserves information about Roman supply networks, settlement patterns and the extent of Roman authority within the Welsh interior during the Imperial period.
