Milan - or Milano, in Italian - is a relatively small town, with Piazza Duomo (or the Cathedral Square) as its historical and geographical umbilicus.
.:.   The city center is enclosed by an inner ring, corresponding to the walls which protected Milan during the Middle Ages. (Those walls, by the way, are no longer there).
.:.   A wider area is enclosed by the ’Viali’ or ‘Bastioni’, the ring of the 16th-century Spanish Walls (almost completely gone, too). Driving in this area involves a congestion charge.
.:.   The area outside the Bastioni is more recent. Its outer boundary is the Circonvallazione Esterna where trolley-buses run, a ring made up of the alleys around the near outskirts.
.:. Further out the real outskirts begin.
