Château de Lourmarin was originally a 12th-century fortress which was transformed in the 15th century by Foulques d'Agoult, chamberlain of King Rene I. of Anjou. After 1526 the castle belonged to Louis d’Agoult-Montauban and his wife Blanche de Lévis-Ventadour and the new annex made the building the first Renaissance building in the Provence Region.
Afterwards the castle became the residence of the Créqui-Lesdiguières family, who were the lords of Château de La Tour d'Aigues. Despite owning the castle, they never took residence in it, and this state of affairs continued until the beginning of the French Revolution.
After the Revolution, and despite having two more owners, the castle slowly descended into ruins.
Finally, in 1920, Robert Laurent-Vibert, a producer of cosmetics, bought the ruined castle and employed the architect Henri Pacon to restore it. In 1925, Laurent-Vibert died in a car accident. In his will he donated the castle to the Académie des Sciences, Agriculture, Arts et Belles Lettres under condition that it should be transformed into a trust, which would support young artists.
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.
