Tomen y Mur is a Roman fort and associated settlement located in Meirionnydd, Gwynedd, Wales. The site comprises a Roman auxiliary fort dating to the second century AD, with a distinctive motte-and-bailey earthwork constructed in the medieval period overlying the Roman remains. The fort formed part of the Roman military infrastructure in Wales and served to control the local population and maintain communications along the inland routes of the province. The survival of both Roman and later medieval features at the site makes it significant for understanding long-term patterns of occupation and the strategic importance of this location across different periods.
