Welsberg Castle (Castel Monguelfo in Italian) lies in a strategic position above Casies Valley. The castle was built in 1140 by the two brother Schwinkher and Otto von Welsberg. This latest wanted the overhanging upon his lands. For more than 800 years the castle had been property of the von Welsbergs, one of the mightiest families in Tyrol, who obtained the title of Prince of the Holy Roman Empire in 1693 by the emperor Leopold I.
The construction can be divided into two main periods: the first Romanesque one in the XII century, and the second one, in the gothic and Renaissance period in the XVI century. The oldest element of the castle is the tall defensive tower built between 1126 and 1140. Around it the old Romanesque chapel, the residential building, and the other buildings had been built.
In 1765 the castle was destroyed by a fire and the upper floor had to be broken up and the roof brought down to the present height. Since then the castle had been forgotten till recent times when the heir of the Welspergs entrusted it to the Kuratorium Committee which completely restored it and made visits available during summer season.
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.
