The 12th-century abbey where the Mona Lisa was hidden

Loc-Dieu Abbey, situated in the Aveyron region of France, was named Locus Diaboli ('devil's place') due to the numerous dolmens nearby. The monks who founded it in the 12th century renamed it Locus Dei ('the place of God'). The abbey was burnt down by the English in 1409, rebuilt and fortified in 1470, suppressed by the French government and its assets sold off during the French Revolution in 1793. The Cibiel family bought it in 1812, and they, along with their descendants, still reside in the abbey today. The buildings were restored in 1840 and 1880. A significant event in 1940 saw paintings from the Louvre, including the Mona Lisa, being hidden here to keep them safe from German troops. The abbey and its vast park are now open for visitors.
