Prince Emanuele Filiberto of Savoy-Aosta, 2nd Duke of Aosta (1869-1931) was a member of the House of Savoy, and a cousin of Victor Emmanuel III of Italy.
During the First World War the Duke of Aosta commanded the Italian Third Army, which gained the nickname of Armata invitta (“undefeated army”). Following the war he was promoted to the rank of Marshal of Italy by Benito Mussolini in 1926.
Prince Emanuele Filiberto died in 1931 at Turin; accordingly to his will, he was buried in the military cemetery of Redipuglia, together with thousands of soldiers of the Third Army.
Entitled to him were the Duke of Aosta Bridge in Rome, built in 1942, and this memorial, located in Turin (I’ll show you other pics of this huge memorial over the next days).
This memorial was inaugurated in 1935. I even found on Youtube a video of the Istituto Luce about an exhibition of the different proposals filmed in 1933:
