Seville – the river port and the monopoly of trade
The heart of Seville’s American role was the river port on the Guadalquivir. Ships were prepared, loaded and unloaded along the Arenal. The Reales Atarazanas (shipyards and arsenals, 13th–18th centuries) supplied and repaired vessels. Two defensive towers still mark the old port area: the Torre del Oro and the Torre de la Plata. Nearby sections of the Arab wall formed part of the customs zone where incoming merchandise was controlled before being taken to the Casa de la Contratación.
The Casa de la Contratación itself was installed inside the Alcázar. From here the Crown regulated the fleets, licences, cargoes and passenger lists. Precious metals were taken to the Casa de la Moneda (the Mint), where contemporary witnesses described quantities of gold and silver that astonished European visitors.
