Zamora is a city in Castile-Leon, Spain, the capital of the province of Zamora. It lies in the northwest, near the frontier with Portugal and crossed by the Duero river. The name Zamora comes from the Visigoth “Semura” or from the Arab “Azemur” and “Semurah”. The foundation of the city, however, was by Rome, with the name of Occelum Durii or Ocellodurum (the Duero Eye), in the days when the local hero Viriathus fought the Roman invasion. At Roman conquest, it was in the hands of the Vaccaei, and was incorporated into the Roman province of Hispania Tarraconensis. It was on the road from Emerita (modern Mérida) to Caesaraugusta (modern Zaragoza ).
