Torre XX Settembre
Italy
The 186th tallest tower in the world
Torre XX Settembre, in Turin, is one of the earliest examples of Modernist skyscraper in Italy. The building was designed in 1939 by Gino Salvestrini and Gabriello Gabrielli di Quercita. Because of the outbreak of the Second World War, however, works started only in 1947 and were completed in 1951.
