San Salvatore is one of the largest castles in northern Italy. In 1245, the city of Treviso granted the hill of San Salvatore to the Collalto family. They built a castle on top of the hill between the late 13th and early 14th centuries. In 1312, when the castle was complete, Emperor Henry VII granted full jurisdiction of the area to the Collalto family. They planted vineyards in the fields around the castle.
The 16th to 18th centuries were a peaceful period in the area, and the castle was embellished by a number of artists. Its chapel was decorated with frescoes, and a palace called Palazzo Odoardo was also built within the castle.
Following the Battle of Caporetto in 1917, Susegana fell under Austro-German occupation. The castle was used by the occupation forces, and was later bombarded by Italian artillery, severely damaging the structure in the process. The castle was restored between 1943 and 1951.
The castle is now used as a venue for cultural events.
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.
