Inner Ring Road, the "Cerchia dei Bastioni" of the 16th century Spanish Walls (now marking most of Milan's "Area C" for traffic control)

The inner ring road is a ring road of Milan that has an ancient origin from physical historical structures rather than just being conceptually patched together on a planner's draft board from existing routes.

This next ring road further in from the external ring road is, quite logically, the "Circonvallazione interna" inner ring road (SEE ALL of the ring roads on the interactive Milanfinally Ring Roads of Milan Google Map). This circular route of roads mostly follows Milan's old Cerchia dei Bastioni (Circle of Bastions) along the old "Spanish Walls": "The so-called 'Mura Spagnole' (Spanish Walls) of Milan were built between 1546 and 1560 in obedience to the will of Ferrante Gonzaga, city governor during the Spanish rule of Milan". Some sections of the Spanish Wall have been preserved. This inner area largely corresponds with the new Area C in Milan used to levy a congestion charge on traffic.

The gates in the old Spanish Walls of Milan, with many familiar names of present day districts (See this image in the Italian article on the Gates of Milan in The Inner Ring Road now follows the course of this "Circle of Bastions".

Many important districts have corresponding names to the gates of these "Spanish Walls" (many of the large and ornamented gates that are still standing were built in later Napoleonic times, and a number of gates have been given new names since those Spanish time - clockwise from the north): Porta Garibaldi (was Porta Comasina), Porta Nuova, Porta Venezia (was Porta Orientale or Porta Renza), Porta Vittoria (was Porta Tosa), Porta Romana, Porta Ticinese and Porta Magenta (was Porta Vercellina). (All of these seven gates were related to gates in the older Medieval Walls further towards the centre, discussed later in the article on the Milan's Medieval Walls and the Circle of Canals).

Currently, the western half of this circle is served by Tram 19; while the eastern half is served by Tram 9. Both Trams 9 & 19 terminate at Porta Genova in the southeast. No trams run along the short section of the inner ring road in the north between Parco Sempione and Porta Garibaldi.
