The Church of San Martino is located in the chief town of Arnad-Le-Vieux. The current building has a trapezoidal layout, with three naves that preserve a roof made of Gothic, low pointed cross vaults. The pillars support large arches that rest on capitals. The facade has a central tuff portal from the 15th century, decorated with a keel-shaped arch, representing two intertwined tree trunks with an overhead rose window. There are slender, single mullioned windows.
The bell-tower, with a square shape, has a high, pyramid-shaped spire. The ceiling on the left nave is decorated with Late Gothic frescoes. The subjects represented include “St. George fighting a dragon”, the “Feast of Herod”, a “Crucifixion” and the “Beheading of John the Baptist”.The parochial museum houses some interesting sacred objects.
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.
