The current structure of Chiesa Parrocchiale di Saint-Vincent, with a large circular apse, dates back to the 15th century, when important changes were made to a probable, pre-existing Romanesque building. For some time it conserved certain parish church prerogatives (festive functions and cemetery), even though it was never a parish church.The apse vault has a beautiful series of ribbed stone. Recent restoration removed the modern structures and decor, in an attempt to restore the church to its original appearance. In the past, on Easter Monday, the so-called “vineyard procession” took place, which in almost six hours passed through all the villages and chapels on the Saint-Vincent hillside.
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.
