IIn the imperial age,a 13 km long aqueduct was built, which ran through the hill's slopes, crossed three mountains,three tunnels and whose water courses went beyond  over dams and bridges. Subterranea offers the opportunity to walk in "Formina", the only conduit open to the public.

Walking inside a 700 metre long conduit, it's possible for us to understand the difficulties that the workmen had to overcome during the excavation of the rock. We can also admire wonderful sculptures created by the water during the centuries .The exit is through a series of stairs around the wall of a well 18 metres deep.

A change of clothes and shoes after the visit is necessary. The visit isn't recommended for those with a fear of enclosed spaces or for those over 100 kg.

THE ADVENTURE IS ASSURED!
