The Mirabello Castle is located in Mirabello di Pavia in the area of the Parco Visconteo. The building today is only a wing of the original castle, which was the seat of the Captain of the Park, the authority administering the Parco Visconteo on behalf of the Visconti family.
Since the 12th century the area had been occupied by a Cistercians monastery. In 1325 the Fiamberti family of Pavia acquired goods and lands in the area and between 1325 and 1341 they built the original castle. In the sixties of the fourteenth century, Galeazzo II Visconti acquired the castle from the Fiamberti. The castle was completed by the Visconti family and incorporated in the Parco Visconteo.
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.
