Situated in the port of Pornic, Château de Pornic has long been a symbol of the town. The castle is privately owned and not open to the public. The castle is bordered on one side by the sea and is constructed on a defensive site. In the Middle Ages, it provided for the defence of the port.
In the 10th century, Alan Wrybeard, Duke of Britanny, built and fortified a wooden castle. It was occupied by a garrison who protected the entrance to Pornic. In the 12th century, it was the property of the Lords of Rais who rebuilt it in stone. In the 15th century, it belonged to Gilles de Rais but was confiscated by the Duke of Britanny at the time of his trial. In the 18th century, it belonged to Marquis de Brie Serrant whose properties were confiscated during the French Revolution. The castle fell into ruin. The castle was bought at the end of the 19th century by Monsieur Lebreton, founder of the seawater baths, and restored by the architect François Bougoüin who gave it its present appearance with its fully arched windows dressed in brick in the style of the Italian architecture of the Château de Clisson.
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.
