The exact origins of the Cosenza Cathedral are unknown; it was probably built during the first half of the 11th century. An earthquake destroyed the cathedral on 9 June 1184, and rebuilding was completed by 1222 when the cathedral was consecrated by Emperor Frederick II.
At some point during the first half of the 18th century the church was covered by a baroque superstructure which obliterated the original structure and its works of art. In the first half of the 19th century the façade was transformed in neo-gothic style, which completely changed its character. At the end of the 19th century, Archbishop Camillo Sorgente entrusted the work to Pisanti, who recovered the original old arches and the ancient structure of the church. In the 1940s the work was finally completed.
In the transept is the tomb of Isabella of Aragon, wife of king Philip III of France. A long aisle links the Duomo to the archbishops' palace, the Palazzo Arcivescovile, which houses an Immacolata by Luca Giordano. One can also admire the rare and precious Stauroteca, a gift from Emperor Frederick II to the Duomo upon consecration. The work was produced in the royal goldsmiths' workshops, better known as “Tiraz”, in a cultural environment which blended Arabic, Byzantine and Western cultural elements.
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.
