San Michele Arcangelo is a Roman Catholic church located on Largo San Gianuario, in front of the more imposing church of San Gianuario in the town of Marsico Nuovo.
The popularity of churches dedicated to the warrior angel was spread by the Lombards, and this and some documents attest to this church existing centuries before 1131, perhaps in the time of the Duchy of Benevento. The church at the site has undergone many reconstructions over the centuries. Many are due to damage by earthquakes, including one in 1700 cited by a plaque in the belltower.
The present facade was likely the original apse. The main portal in gothic-style dates to the 13th century or earlier, and is attributed to the Master Melchiorre da Montalbano.
The interior has a medieval stone baptismal font and an 18th-century painting on wood of the Archangel. The apse has remains of medieval frescoes showing Byzantine influence.
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.
