A Roman settlement
San Martín del Castañar
Located along the Francia river, on a former Roman settlement, it shows some of the most authentic mountain remains in the area, such as the remains of its wall and the castle, which houses the interpretation center of the Biosphere Reserve.
Its population gathered around its Church, which dates back to the 13th century, and may be a palatial castle in the 15th century, -with close links to the Miranda del Castañar fort-, around which the first houses were concentrated. Of particular note are the bridge of Roman origin, on which an ancient Roman road also runs, leading to the hermitages of Socorro and Humilladero, and the ruined Monastery of Nuestra Señora de Gracia. In addition, we can see an ancient Roman stele in the park of the municipality, an idyllic place to walk and rest.
