Technical visits

A technical visit will be organised to the underground construction sites of the new Metro Line C that underpass the historical centre of Rome. Line C was conceived to link the city’s eastern quadrant to its northwest one. Starting from the Pantano terminus in the Municipality of Montecompatri, the line stretches for about 25.6 Km, approximately 9 of which on the surface and 16.5 underground, cutting through historic city neighbourhoods such as Centocelle, Alessandrino, Pigneto, Appio as well as through the historic centre itself, before reaching the Prati area in the vicinity of Piazzale Clodio. Its completion will make a truly integrated public transport network.

Important historical monuments of Roman Age, such as the Church of Santo Stefano Rotondo, the Anfiteatro Flavio (Coliseum) and the Basilica di Massenzio are mainly encountered along the route of the line. This made the construction process more problematic due to the presence of buried archaeological remains coupled with the need of minimising the impact of tunnelling and deep excavations on the historical and monumental heritage. A visit will be organised to the construction sites of the Metro station at Fori Imperiali along with those of a deep ventilation shaft, close to Villa Celimontana, and of a circular shaft, close to the Aurelian Walls at Porta Metronia. This latter was excavated to install the sleeved grout tubes (tubes à manchette – TAMs) to inject grout in the soil between the tunnel and the wall foundations, in order to compensate for ground loss and stress relief caused by tunnelling.
