Nowadays, one of the best places to observe the remains of the Wall of Mataró is in Xammar Square, in the urban centre of Mataró, in the Maresme region.
The Wall of Mataró was built between 1569 and 1600, and was designed by the military engineer Jorge de Setara. Supposedly, these walls largely follow the line of the old Roman Wall.
They were built with small stones, bound with lime mortar. The wall of Mataró had seven large gates, as well as attached towers that gave it greater defence.
During the 19th century, many sections of this ancient wall were demolished.
