Used as a port by Greeks (who named it Salauris) and Romans, it appeared again in an important historic event, when in 1229 the fleet of James I of Aragon departed from the port of Salou to conquer the Balearic Islands, thus creating the Kingdom of Majorca. In 1286 Alfons III of Aragon also departed from this port to conquer Minorca, the last Moorish territory of the Balearic Islands. Later, Salou became a nest of pirates. After that it was considered an unsafe place, so in 1530 Archbishop of Tarragona decided to erect a new defence tower, now called Torre Vella. In 1865 the railway station began to operate, opening a new development time that led one hundred years later to a tourist boom that has brought prosperity to the town. Salou was separated from the adjacent municipality of Vila-seca on 30 October 1989 by a decision of the Supreme Court of Spain
