Viseu, officially the City of Viseu, is a city and municipality in the Central Region of Portugal and the capital of the district of the same name, with a population of 103,502 inhabitants in the entire municipality, and center of the Viseu Dão Lafões intermunicipal community, with 267,633 inhabitants.
Settled during the period of the early Iberian Castro culture, the territory of Viseu was occupied by a series of other peoples including the Romans, Suebians, Visigoths and Moors. During the Roman occupation of Iberia, Viriathus, the rebel leader of the Lusitanians, is assumed to have lived for a time in the vicinity. During the Middle Ages, the city often served as a seat for Visigothic nobles (such as King Roderic), and based in the Chronica Gothorum is one of several probable birthplaces for Afonso Henriques, first King of Portugal.
