The Central Station of Milan appears imposing on Piazza Duca d'Aosta with statues and an arched portico almost 28 meters high: an architectural work available to the approximately 400,000 people who pass through what is considered one of the most important European railway nodes, as well as the second Italian station in terms of size and traffic. It was inaugurated in 1931 to replace the old central station that stood in the current Piazza della Repubblica, which had become insufficient due to the increase in rail traffic.
