The Cathedral of Syracuse (Duomo di Siracusa) origins on this site date to prehistory. The great Greek Temple of Athena was built in the 5th century BC. The temple was a Doric edifice with six columns on the short sides and 14 on the long sides. Plato and Athenaeus mention the temple, and the looting of its ornament is mentioned by Cicero, in 70 BC, as one of the crimes of the governor Verres.
The present cathedral was constructed by Saint Bishop Zosimo of Syracuse in the 7th century. The battered Doric columns of the original temple were incorporated in the walls of the current church. They can be seen inside and out. The building was converted into a mosque in 878, then converted back when Norman Roger I of Sicily retook the city in 1085. The roof of the nave is of Norman origin, as well as the mosaics in the apses.
As part of the increased building activity after the 1693 Sicily earthquake, the cathedral was rebuilt and the façade redesigned by architect Andrea Palma in 1725–1753. The style is classified as High Sicilian Baroque, a relatively late example. The double order of Corinthian columns on the facade provide a classic example of carved Acanthus leaves in the capitals. Sculptor Ignazio Marabitti contributed the full-length statues on the facade.
The interior of the church, a nave and two aisles, combine rustic walls and Baroque details. Features include a font with marble basin dating from the 12th or 13th century, a ciborium (an altar canopy) designed by architect Luigi Vanvitelli, and a statue of the Madonna della Neve by Antonello Gagini (1512).
The cathedral of Syracuse is included in a UNESCO World Heritage Site designated in 2005.
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.
