Cripta di San Giovanni

It is an outstanding witness of Milan's history and art from the 5th to the 17th century. It was demolished by the Austrians in 1782 and finally closed by the French to store ironware and carriages. Only a small part of the 11th century church has survived to this day. The restored basement shows Roman and medieval objects.

A retained wall in the center of the city feels like a ruin on a corner, with a black monument beside it commemorating the history of what is now only a few brick walls. Underneath the site is a cellar, and the structure of the dome is quite distinctive.

The scenery is beautiful, interesting and the price is reasonable.
