Note about the wall: In the first half of the 12th century the Almoravid rebuilt the walls of the roman city, which was subsequently extended by the Almohads and Christians. A remaining part of this wall encircles half of our local park.
As Seville was built on a river plain, so the large rocks and boulders that the Romans preferred and needed for fortifications were difficult to find, and so the wall was built using the “tapiar” method where lime, sand and smooth stones from the river were mixed into a paste. The mixture was then poured into the wooden structures. Once dry, the wooden structure was removed and the following blocks were started. I’ve noticed small shells in the piece of wall closest to the river in Calle Goles.
