Perched on a rocky outcrop, this islet had been inhabited since the 2nd century AD. The fortified castle, built in the Merovingian period, and the estate was to have countless occupants before coming under state ownership during the French Revolution.
The fort was built in the 13th century and was used for military purposes for most of its life, belonging to a variety of noble families as they fell in and out of power throughout the centuries. The fort was besieged several times and used as a place to escape; Queen Jeanne Ire stayed in 1348 after fleeing Naples, which had been invaded by her cousin – she used it as a pit-stop on her way to taking refuge in Marseille. The fort wasn’t badly affected by the French Revolution, although a few items were plundered by locals.
Napoleon took a liking to the fort and stayed here during the winter of 1793-94. When he became Emperor, he supplied funds to build up the garrison. After the Franco-Prussian war of 1870, the War Ministry allocated money to build an artillery, although they didn’t do much to the outside of the main structure, which was slowly falling into disrepair. It was occupied by a small garrison during World War I until it was finally decommissioned in 1919.
In 1968, General de Gaulle transformed it into one of the official residences of the President of the Republic. The monument houses numerous gifts received by heads of state during France's Fifth Republic.
The Fort de Brégançon served as the official retreat of the President of France until 2013.
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.
