The walls of Seville surrounded the Old Town portion of the city. The first walls were constructed by the Romans almost two millenia ago. The walls were maintained and updated over the centuries and portions of them still remain, especially around the Alcázar and in the barrio de la Macarena.
This section of the old wall likely dates to the 12th century Moorish period of the city, although it was modified about 200 years ago. It contains one of the city's few surviving gates.
