In 1589, Maréchal de Villars supervised the construction of a small fort on the hill known as 'colline des Moulins' overlooking Saint-Tropez. This fort was destroyed in 1595, but the military engineer Raymond de Bonnefons chose the same site to build further defensive structures from the start of the 17th century.
The hexagonal tower, which formed an essential part of the village's defence system, was erected between 1602 and 1607. The Citadel underwent numerous modifications over the centuries, before falling into disuse in the 19th century, when the strategic interest of this perfectly-preserved fortress finally diminished.
The old cannons are still in place facing out towards to sea, and the views from the top are stunning across the Gulf and the Mediterranean Sea.
Bought up by the town in 1993 and made a listed monument, today it hosts a museum dedicated to the history of Saint Tropez and its relationship with the sea.
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.
