[2] Chantada is situated on the left bank of the Río Asma, a small right-hand tributary of the Minho river, and on the main road from Ourense, 29 km S. by W., to Lugo, 45 km N. by E.[2] Chantada is the chief town of the fertile region between the Minho and the heights of O Faro, which mark the western border of the province.

Located close to the branch Chaves-Lugo of the Via Bracara Asturicam, that connected the modern cities of Braga, in Portugal, and Astorga, in Castilla y Leon,[4] Chantada has numerous vestiges of the Roman presence in the zone, like the fortified village of Castro Candaz.

According to the documentation belonging to the Camba's house, Castro Candaz was founded by the Roman consul Lucio Cambero.

[5] He was related to the "Galician mountain people", who would fight along with the tribe of the Aunonians against two Roman legions sent by Emperor Trajan.

According to Formoso Lamas, during the second strike of Norman invasions, the Vikings overcame Mount Faro and reached Chantada, where a fence was erected (Plantata).
