Ponte di Ronciglione

Ponte di Ronciglione is a railway bridge spanning the Rio Vicano valley with two symmetrical parabolic arches that require no central ground supports. The steel structure stretches approximately 119 meters and demonstrates the engineering approach of the period.

The bridge was constructed from 1925 to 1928 following a design by Swiss engineer Jules Röthlisberger, built by Società Nazionale Officine di Savigliano. The project applied construction principles developed by Gustave Eiffel.

The bridge appears in several Italian films, including 'Un giorno da leoni' and 'Baciami piccina', where it represents local engineering skill. Filmmakers used its distinctive shape to create dramatic scenes within the landscape.

The bridge can be observed from several vantage points within the valley, and parking areas with information signs are located nearby. The best views of the structure come from different angles throughout the surrounding area.

This bridge belongs to a rare group of only nine similar iron arch structures worldwide. Its parabolic arches make it a remarkable example of early 20th-century steel bridge engineering.
