The Château de Lacoste origins are in the 11th century, but it was largely modified in subsequent centuries. It was for many years the property of the Simiane family.
In 1627, Diane Simiane married Jean-Baptiste de Sade, ancestor of the Marquis de Sade, who thus became owner of the estate. The Marquis de Sade stayed there from 1769 to 1772, between the scandals at Arcueil and Marseille, then after the latter and his flight to Italy, he took refuge there until his incarceration in the Château de Vincennes in 1777. Escaping while being transferred to Aix, he took refuge there for the last time from 16 July to 7 September 1778 before being returned to Vincennes.
It was in 1772 that he made his longest stay there, during which he built in the castle a theatre capable of holding 120 spectators. Throughout his internments, he maintained an extraordinary attachment (un attachement extraordinaire) for La Coste.
De Sade described Château de Lacoste in two of his works – La Marquise de Ganges and Les cent vingt journées de Sodome (The 120 Days of Sodom) – under the name of the Château de Silling.
During the French Revolution, the castle was vandalised and largely destroyed. The construction materials were sold. Crippled with debts, in 1796 the castle and its estate were sold to Rovère, deputy of Vaucluse and a native of Bonnieux, who, a victim of the Coup of 18 Fructidor, was deported to French Guiana where he died at Sinnamary in 1798.
The castle offers superb views over the valley of the Calavon, the Monts de Vaucluse, Mont Ventoux and the Alps, as well as the village of Bonnieux which can be seen on a neighbouring hill.
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.
