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:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
