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:
Roman Walls of Lugo are an exceptional architectural, archaeological and constructive legacy of Roman engineering, dating from the 3rd and 4th centuries AD. The Walls are built of internal and external stone facings of slate with some granite, with a core filling of a conglomerate of slate slabs and worked stone pieces from Roman buildings, interlocked with lime mortar.
Their total length of 2117 m in the shape of an oblong rectangle occupies an area of 1.68 ha. Their height varies between 8 and 10 m, with a width of 4.2 m, reaching 7 m in some specific points. The walls still contain 85 external towers, 10 gates (five of which are original and five that were opened in modern times), four staircases and two ramps providing access to the walkway along the top of the walls, one of which is internal and the other external. Each tower contained access stairs leading from the intervallum to the wall walk of town wall, of which a total of 21 have been discovered to date.
The defences of Lugo are the most complete and best preserved example of Roman military architecture in the Western Roman Empire.
Despite the renovation work carried out, the walls conserve their original layout and the construction features associated with their defensive purpose, with walls, battlements, towers, fortifications, both modern and original gates and stairways, and a moat.
Since they were built, the walls have defined the layout and growth of the city, which was declared a Historical-Artistic Ensemble in 1973, forming a part of it and becoming an emblematic structure that can be freely accessed to walk along. The local inhabitants and visitors alike have used them as an area for enjoyment and as a part of urban life for centuries.
The fortifications were added to UNESCO"s World Heritage List in late 2000 and are a popular tourist attraction.
