Viana do Castelo, the place where, in 1258, D. Afonso III established the village that was called Adro. The monarch appointed him Viana, which would already be his previous name; D. Dinis called it Viana de Riba do Minho; D. Afonso V identified her by Viana de Cerca de Caminha. In other documents it is called Viana de Foz do Lima, Viana do Lima, Viana do Minho, Viana de Caminha (D. Manuel 1492) and Viana de Foz do Lima (D. João III, 1522). The toponym Viana may be related to Austrian Wien and French Vienne, or it may be related to the designation of nearby towns, such as Villa de Vinea and Ovinia, perhaps resulting from personal names.
