Château de Saint-Malo was built between 1424 and 1690, first by Jean V, the Duke of Brittany. The Duke Francois II built the first tower in 1475. In 1590 during the Wars of Religion the castle was occupied by local people, who wanted to prevent local governor to gave the city to Protestant king Henry IV.
The château was modified in the 17th century according the design of famous fortress architect Sebastian Vauban. In the 19th century it functioned as barracks. Today it is a museum, covering a number of themes including the long maritime history of St-Malo, 19th century writers of which Chateaubriand is the most well known, WWII occupation and the destruction and reconstruction of the town.
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.
