Italy used the opportunity to expand the event with an exposition celebrating the centennial of Italian unity.
The international part of the Expo 61 was held in the purpose-built Palazzo del Lavoro (Labour Palace) designed by the Italian architect Pier Luigi Nervi.
The Italian part of the Expo 61 was located between the Palazzo del Lavoro and the car museum, two kilometers north.
Visitors could use a monorail for an 1800m ride between the northern entrance at the car museum and the Palazzo del Lavoro at the south side of the exposition.
An aerial cableway provided access to the Parco Europa, a viewpoint at the other side of the Po.
