Nicastro Cathedral is a Roman Catholic cathedral in the town of Nicastro, now part of the city of Lamezia Terme. It was previously the episcopal seat of the Diocese of Nicastro and when the diocese changed its name to the Diocese of Lamezia Terme, remained its cathedral.
The first church on the site probably dated from the Byzantine era, and was destroyed during Saracen raids prior to the year 1000. The Normans in 1094 erected a church following Latin rites. This cathedral was destroyed by an earthquake on March 7, 1683. A new cathedral was raised from the ruins and completed in 1675. The façade was redone in 1925 in a Neoclassical style. The cupola was completed in 1935. On the façade are busts depicting the titular saints and popes Marcello II (Marcello Cervini; 1539-40) and Innocent IX who were bishops of Nicastro. The wooden choir stalls of the early 18th century are still present.
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.
