The small St Proculus church near Naturno is undoubtedly a historical treasure. It dates back to the 7th century AD and features the probably most ancient frescos of the German speaking area and the most complete early fresco cycle of Tyrol. Furthermore there are some Gothic frescoes from the 14th century.
The building itself has been established between 630 and 650 AD. The age of the oldest pre-Carolingian frescoes, however, is rather contested, new datings refer to the period of time between the 7th and 10th century. The most famous fresco shows a man on a swing, probably St Proculus himself.
Only a stone’s throw from the chapel, there is also the Proculus Museum, which has been inaugurated in 2006. The museum is allocated subterraneously and takes visitors into 1,500 years of history of the area around Naturno. Four time-space showrooms take you across late antiquity, Middle Ages and early modern times. Moreover in the museum you can admire the Gothic frescoes which have been taken down from the walls of the St Proculus church.
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.
