The Church of Saint John is one of the oldest in the city. It is estimated that it was built during the second half of the 11th century on an old mosque.
In the 18th century, the remains of a Roman cemetery were found in its crypt. This served as proof to determine that there was one of the gates of the Roman wall, as these fortifications had four gates, and a cemetery was located on the outskirts of each of them.
During the 19th century, the church fell into disrepair and its architecture was seriously damaged during the Spanish Civil War. At that time, their funerary crypts were adapted to be used as an anti-air shelter, and the radio station "Radio Telegrafos" was installed on its premises. It was run by Republican Andalusia, which had the mission of interfering with Radio Sevilla broadcasts.
In 1952, the Church of Saint John, inside of which the parish of Saint Peter is located, was declared in ruins. Then the cult was transferred to the Royal Monastery of Saint Clare. The interior was demolished and replaced by a concrete structure. This new temple, which was completely devoid of architectural significance, was opened for worship on May 29, 1956.
Already in the 1980s, to improve the appearance of the temple, works were carried out that sought to harmonize the architectural ensemble with its undoubted historical relevance.
