St Fanourios Church was built in the 13th century. It’s cross shaped and the interior is adorned with wonderful frescos. It officiated as a mesgit (small mosque) during the ottoman occupation. There is no known testimony for its name before the ottoman period. The interior was preserved in the 20’s by the Italian Archaeological Service. After the World War II, Greeks took over the church. In 1946 the church was inaugurated and dedicated to Agios Fanourios.
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.
