Before they were sealed off, the tunnel network had been an integral part of the city since the days of Ancient Rome.
They were further developed in the Middle Ages and were in use as recently as the 1920s.

Some parts of the network are lined with bricks, which the broadcaster says shows signs of development and use in the 19th century.
Work to make the tunnels ready to receive tourists and visitors is currently underway.
Archaeologists had used laser scanning to map the spaces through out the vast complex.
"The proposed interventions are aimed, on the one hand, at safeguarding the monument, through the restoration and safety of the structures, and, on the other, at enhancing its accessibility and usability, which is currently extremely limited," a spokesperson for project lead Insula architecture group said.
"The Campidoglio Grottoes project envisions conservative restoration and enhancement of the underground passageways and cavities that wind through the hill, crossing it in various directions and on multiple levels."
This work includes managing the release radon gas, which comes from the area's volcanic rock.
It will see specialist filters installed at the site to ensure it is safe.
There will also be a museum space on the upper level, as well as disabled access for visitors.

In one part of the tunnels, it is even possible to see the foundations of the Temple of Jupiter.
