The medal commemorates the construction of this extremely important work which came to connect the town of Albano Laziale with Ariccia, the ancient city already mentioned in the times of Tarquinius Superbus. The grandiose viaduct with three rows of arches, 300 meters long and 59 high, which boldly spans a valley formed by an extinct volcanic crater, was designed by the architect Giuseppe Bartolini. The works begun in 1847, ended in 1853 and the inauguration was carried out by the Pope on October 12, 1854. The bridge, destroyed on June 3, 1944 during the Second World War, was rebuilt in 1947.
