Piazza Armerina Cathedral is dedicated to Mary of the Victories (Maria Santissima delle Vittorie). It is the seat of the Bishops of Piazza Armerina.
Built on the foundations of an earlier church of the 15th century and based on a design by architect Orazio Torriani, its construction began in 1604 and ended in 1719, while the dome was added in 1768. It became the seat of the Diocese of Piazza (later Piazza Armerina) when it was created in 1817.
The interior of the cathedral is dominated by the central dome. It contains a cross painted on both sides, showing the crucifixion and resurrection of Christ, and a baptistery by Antonello Gagini.
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.
