The Walls of Seville are a series of defensive walls surrounding the Old Town. They were built in times of Julius Caesar, approximately between the years 68 and 65 BC, when he was quaestor of the city. This new fortification was aimed at replacing the old Carthaginian stockade of logs and mud. The walls were expanded and refined during the rule of his son Augustus due to the growth of the city.
The city has been surrounded by walls since then and they were maintained and modified throughout the subsequent Visigoth, Islamic and finally Castilian periods. The walls remained intact until the 19th century, when they were partially demolished after the revolution of 1868. Some parts of the walls still exist, especially around the Alcázar of Seville and some curtain walls in the barrio de la Macarena.
The walls originally had eighteen gates or points of access, four of which survive today: Puerta de la Macarena, Puerta de Córdoba, Postigo del Aceite and Postigo del Alcázar. The extant parts of the walls maintain an Almohad appearance, mixed with Classicist air resulting from restorations carried out in the 18th century.
