(b. 1762, Milano, d. 1833, Inverigo)
Arco di Sempionebegun 1806
Piazza Sempione, Milan
The Arco di Sempione (Arco della Pace) was constructed by Cagnola to mark the wedding of the Viceroy with Augusta Amalia of Bavaria, originally as an ephemeral structure but later rebuilt in stone. Begun in 1806, at the same time as the Arc de Triomphe de l'Étoile in Paris, with which it is closely related, the triumphal arch is based on the ancient arch of Septimius Severus in Rome. Like the Arc de Triomphe de l'Étoile, it remained uncompleted after the fall of Napoleon. After a long lull, it was completed in 1838 as the Arco della Pace, but then renamed Arco di Sempione in 1859 on the occasion of a peace treaty with France.
