Château de Cadillac is located at 35 km from the city of Bordeaux, it overlooks the Garonne river and the walled town of Cadillac. The monument was built at the request of Jean-Louis de Nogaret de la Valette (1554-1642), first Duke of Épernon, its primary function was to house the Dukes of Épernon. The castle thus embodies the all-powerful duke, who amasses wealth and honors before he died in disgrace during the reign of Louis XIII.
The building is both a witness of the late Renaissance, but also announces the classicism of the XVII century. Originally, the castle and two wings surrounding a courtyard on three sides, it notably has carved stone fireplaces and marble, painted ceilings of the XVII century tapestries, which testify to the splendor of the residence. Seized during the French Revolution, he served as a prison for women, then a psychiatric hospital. The castle has been reopened for tourists.
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.
