Among the many enduring mysteries of this period is the fate of the world’s most famous painting. It seems that Leonardo da Vinci’s Mona Lisa was among the paintings found in the Altaussee salt mine in the Austrian alps, which was converted by the Nazis into their secret stolen-art warehouse.
The painting only “seems” to have been found there because contradictory information has come down through history, and the Mona Lisa is not mentioned in any wartime document, Nazi or allied, as having been in the mine. Whether it may have been at Altaussee was a question only raised when scholars examined the postwar Special Operations Executive report on the activities of Austrian double agents working for the allies to secure the mine. This report states that the team “saved such priceless objects as the Louvre’s Mona Lisa”. A second document, from an Austrian museum near Altaussee dated 12 December 1945, states that “the Mona Lisa from Paris” was among “80 wagons of art and cultural objects from across Europe” taken into the mine.
The Mona Lisa was actually stolen in 1911, in one of the cleverest art heists ever pulled.
