Gräfsnäs Castle today consists of a heavily restored main building with barred windows and surrounding dry moat. The ruins are remnants of the original palatial fortress built in Swedish-French Renaissance style. The castle, which met with such a tragic fate, was constructed in c. 1571 and belonged to many different owners (like Leijonhufvud, Sparre and Holstein-Augustenburg families) before it was finally abandoned in the late 19th century. The tragic coincidence was that Gräfsnäs was damaged by fire in every one hundred years (1634, 1734 and 1834).
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.
