It is an ancient Roman town. Lying on the shores of the Straits of Gibraltar, the town was originally a fishing village and trade link when it was settled some 2,000 years ago. Although prosperous at the time of Emperor Claudius, it went into a decline hastened by earthquakes and was abandoned by the 6th century.
