Porta Nuova is one of the three medieval gates of Milan that still exist in the modern city. It is sited along the ancient "Navigli Ring" on the perimeter of the medieval walls of the city.
Originally built in the twelfth century, Porta Nuova was restored in the nineteenth century with the insertion of two lateral passages next to the two central arcs and the addition of some ancient Roman steles on the external facade of the gate.
The external facade, overlooking Cavour Square, preserve the original appearance with a marble shrine of the Madonna and Child with Saints.
