The Salvador church was erected on the remains of the Ibn Adabba, the Great Mosque of Muslim Seville (9th century). This religious temple, as well as its surroundings, had great importance in the daily life of the people, which is why when the Christians conquered Seville, they allowed it to be used as a mosque in the beginning, but in 1340, it was converted into the parish of Salvador.
In addition, it was agreed to maintain the ostentatious rank of the second temple of the city; for it was granted a collegiate character. Thus, this building would continue to be used religiously until 1671, when the passage of time left it strongly deteriorated. Its construction as we see it today began in 1674 with the architect Esteban García. Work ended in 1712 under the architect Leonardo de Figueroa.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
