The walls of Seville were military fences that surrounded the old town of the city of Seville. Throughout history, Seville has had several walled enclosures. As it grew, the oldest references to the existence of walls appear in the Roman period.
The existence of a first enclosure of Roman origin is known, of which no visible vestiges remain, which would encompass the south-eastern quadrant of the current historic center (area from Puerta Jerez to San Martín, Encarnación, Puerta Osario, Puerta de la Carne and Alcázar). . The only remains detected correspond to chance finds in the subsoil of the city, these data, together with the observation of the current urban topography, which have allowed us to draw a hypothetical route of the first wall of Hispalis.
The walls that are currently preserved belong to the last defensive system built in the 12th century, mainly by the Almohads; Nothing remains of the Roman wall, only material reused in the Caliphal or Taifa era mainly, which also would not cover the same space as the current one since the city was much smaller.
