Construction of Torino Porta Nuova began in 1861, when Turin was the capital of Italy, under the direction of the engineer Alessandro Mazzucchetti. The station opened to the public in 1864, and construction was finished in 1868, although the capital had been moved to Florence in 1865, and would change again to Rome in 1870. It is still the third busiest railway station in Italy, with about 70 million travellers passing through each year.
