Raudonė Castle construction works started in late 16th century, during the reign of King Sigismund II August. A new renaissance castle was built on the ruins of the old one by a German knight, Hieronymus Krispin-Kirschenstein. The castle has since been rebuilt many times. The 18th century Polish owners of the Raudone estate, the family Olędzki (Olendzki) h. Rawicz commissioned Wawrzyniec Gucewicz with a renovation of the castle. The next owner, the Russian Prince Platon Zubov, acquired the estate in the first half of the 19th century and his family transformed the castle yet again. Their architect was Cesare Anichini.
Today the building is an example of 19th century neo-Gothic architecture. Its last private owners were Sophia Waxell (a Zubov) and her Portuguese husband from Madeira, José Carlos de Faria e Castro. The original castle is the setting of an East Prussian legend known as 'The White Maiden of the Bayersburg'.
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.
