With 27 km in length and 38 stations, is one of the pillars of the entire system of urban transport and surfed. Line 1 accounted for engineering and industry Italian first great experience in the construction industry urban underground and allowed to practice studies and experiments developed by the technicians of MM with the Technical University and the company ICOS. This collaboration has led to the definition of "Milan Method", a drilling system became very famous in the field and later used in the construction of other metros in the world. Among the most important engineering works remembers the intersection between lines 1 and 2 in the stretch Cairoli - Cadorna with the construction of a single large curve radius, which required the opening of two openings in the walls of the Castello Sforzesco and the Crossing the line near the foundations of the Filarete tower. The construction of Line 1 also inaugurated the season of archaeological discoveries and the discovery of historical sites around the city of Milan.
