Milan, subway tunnel opens at Sant'Ambrogio: you can see the ancient city walls

Starting today, Milan citizens and tourists moving between the M2 and M4 subway stations in Sant’Ambrogio will be able to take advantage of a new tunnel that allows them to switch from one line to the other without having to go outside. This is an important step in the continuous evolution of Milan’s subway network, which is enriched with a modern infrastructure, but at the same time bears witness to the city’s history, thanks to the presence of unique archaeological remains.

The tunnel, in fact, is not only a functional link, but also an ... opportunity to discover Milan’s past. Indeed, along the route, passengers will be able to admire the remains of the ancient medieval walls discovered during excavations, thanks to the installation of transparent panels that allow optimal visibility of the archaeological discoveries. These walls date back to the period of the rule of Frederick I Barbarossa, who, after destroying most of the city in 1157, ordered the construction of a new defense system. The walls were in fact intended to protect not only the ancient core of Milan, but also the villages that had meanwhile developed beyond the Roman walls, following the moat created to defend the city.

Arianna Censi, Milan’s Councillor for Mobility, said, “This is another neuralgic point of the M4 connections being opened. Step by step we are with finishing all the superficial works and we are giving back to the city the spaces we had occupied to build this immense work. An infrastructure that is already proving its importance in Milanese mobility and urban public transport.” The M4, the new blue metro line, is becoming increasingly integrated into the city’s network, improving accessibility and fluidizing traffic flows.

The new tunnel is just the latest chapter in a long project to expand and improve Milan’s metro network, which aims to make the city even more connected and accessible.
