Viseu (Portuguese pronunciation: [viˈzew]) is a city and municipality in the Centro Region of Portugal and the capital of the district of the same name, with a population of 100,000 inhabitants, and center of the Viseu Dão Lafões intermunipical community, with 267,633 inhabitants.Settled during the period of the early Iberian Castro culture, the territory of Viseu was populated by a series of cultures including the Romans, Suebs, Visigoths and Moors. During the Roman occupation of Iberia, Viriathus, 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 seat for Visigothic nobles (such as King Roderic), and is considered one of the probable birthplaces of Afonso Henriques, first King of Portugal.
