Bergamo is an Italian city northeast of Milan, in the Lombardy region. Its older upper district, called Città Alta, is characterized by cobblestone streets, encircled by Venetian walls and accessible by funicular. It’s home to the Duomo di Bergamo, the city cathedral. Also here are the Romanesque Basilica di Santa Maria Maggiore and the grand Cappella Colleoni, a chapel with 18th-century frescoes by Tiepolo.
