The Plaza de las Monjas is a space near the Convent of the Augustinians, originally called Plaza de San Juan.
In the 17th century, it faced the back of the Palace of the Dukes of Medina Sidonia. It was used for the town's celebrations, births of the dukes' children, bullfighting events, and other events.
In 1907, municipal architect Francisco Monís y Morales was commissioned to transform it into a public space, adding furnishings and lighting. It has undergone significant transformations over the years, enriching its monumentality. These include the addition of the Fuente Magna in 1942, the 1967 project by Alejandro Herrero, and the 1988 project by Alfonso Martínez Chacón.
In 2006, pedestrianization began, which later connected it to Gran Vía. In 2011, a statue of Christopher Columbus was added.
