The first three of these were later refounded, about 40-20 B.C .-- whether their streets were then laid out afresh is an open question--and Turin and Brescia were added.

In addition, Verona, Pavia, and Como won municipal status in or before this later date, though when or how they came to be laid out symmetrically is not certain.[69] And there are other less certain examples.
[69] Milan (Mediolanium), once the chief Roman town of north Italy, is usually stated to preserve to-day no trace of Roman street-planning.

But the line of the Via Manzoni, Via Margherita, and Via Nerino (cutting the Ambrosian Library) seems really to represent one of its main streets, and the line of the Fulcorino and Corso di Porta Romana the other, while one or two traces of 'insulae' can be detected near the Ambrosian Library.

The town was destroyed in A.D.539 and again in 1162, and more survivals cannot be expected.
Other instances, but not so many, may be quoted from south of the Apennines.

At Florence, for example, and at Lucca 'coloniae' were planted full-grown and the street-plans still record the fact.
