One of the interesting historical sites that attract tourists and visitors of Seville's ancient city walls surrounding the old city and partially extant. The city walls were built as defensive fortifications, and their construction continued throughout the history of Seville - in the times of the Visigoths, the Arab invasion and the reign of the Castilian kings. It is known that the city walls included eighteen gates that provide access into the city, but so far they have survived only four – Macarena gate, Cordoba, Aceite and the Alcazar.
The construction of the walls began in the era of the Roman Empire, during the reign of Julius Caesar, between 65 and 68 A. D. the Walls were built on the site of the old wooden palisade that surrounded the town. In 844 during the rule of the Arab Caliphate, the city and the surrounding walls were destroyed by the Vikings, after which they were restored by order of the Emir Abderrahmane II. After that the walls of the city was several times destroyed and rebuilt anew. In the 11-12 centuries the city walls were expanded and strengthened considerably. By the time of the Christian conquest of the city by king Ferdinand in 1248 the city walls included 166 towers and gate 13. During the reign of king Charles I was an overhaul of the walls, towers and gates.
Over time, the city walls lost their defensive function, and were used mainly for protection from floods during the flood of the Guadalquivir, as well as for commercial purposes, because there was introduced a special fee for entering the city.
