San Pietro de' Cassinensi (outside the Porta Romana) is a basilica with nave and aisles, founded in the beginning of the i 1th century by San Pietro Vincioli on the site of a building of the 6th century, and remarkable for its conspicuous spire, its ancient granite and marble columns, its walnut stall-work of 1535 by Stefano de' Zambelli da Bergamo, and its numerous pictures (by Perugino, &c.).
It flows by Lodi and Pizzighettone, and receives the waters of the Brembo, descending from the Val Brembana, and the Serio from the Val Seriana above Bergamo.
With the exception of a few subAlpine districts near Bergamo and Brescia, the great Lombard plain is decidedly unpastoral.
The Bergamo sheep is the largest breed in the country; that of Cadore and Belluno approaches it in size.
Parmesan is not confined to the province from which it derives its name; it is manufactured in all that part of Emilia in the neighborhood of the P0, and in the provinces of Brescia, Bergamo, Pavia, Novara and Alessandria.
