Founded in 1123 in a place formerly called Locus Diaboli (Latin for 'devil's place') due to the large number of dolmens around it, tm abbey was renamed Locus Dei in Latin by the monks, which in French became Loc-Dieu, both meaning the 'place of God'.
Burnt down by the English in 1409, it was rebuilt in 1470, and the abbey was fortified.
The abbey was suppressed and its assets sold off as national property by the French government during the French Revolution in 1793. The Cibiel family bought it in 1812, and Cibiel descendants still live in it today.
The buildings were restored in 1840 (the east wing) and in 1880 (the south and west wings).
In the summer of 1940, paintings from the Louvre, including the Mona Lisa, were hidden in Loc-Dieu to keep them safe from German troops.
The abbey and its large park are now open to visitors.
Built between 1159 and 1189, the church remains intact. This is one of the first Gothic buildings in southern France, designed by architects from Burgundy. Cistercian rules are followed, i.e. the greatest simplicity possible, with no decorations other than the stone and light. Cloister and Chapter room, rebuilt in 1470, replaced the previous Romanesque cloister. They present a strong Gothic style.
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.
