The parish of San Vittore (St. Victor) is mentioned for the first time in the papal bull dated 5th April 1145 with which pope Eugene III took the canons of Saint-Gilles di Verrès under his protection. The parish church of San Vittore is rectangular in shape and has a single nave. The current church dates back to the end of the 15th century or the beginning of the 16th century and was consecrated in 1521. Its construction was financed by the counts of Challant, whose coat of arms may be observed on a keystone above a buttress.
The facade was rebuilt in 1670 and has a portico to protect the entrance. The seventeenth century portal in cut and sculpted stone is noteworthy and on the inside, the baroque altars in painted and gilded carved wood, are also interesting. The walnut stalls of the choir may be dated back to the end of the 17th century and bear the coats of arms of many of the noble families from the parish. With the new direction of the church beginning from the seventeenth century, the bell tower came to find itself behind the apse. Having collapsed in 1755, it was rebuilt in 1762 but it appears to have kept its medieval typology in the lower section.
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.
