Bergamo, a picturesque city in Italy's Lombardy region, is renowned for its Città Alta, or Upper City. This historic area, encircled by Venetian walls, is known for its charming cobblestone streets and medieval architecture. Visitors can explore the Piazza Vecchia, the heart of the old city, and enjoy panoramic views of the surrounding plains and the modern lower city, or Città Bassa. Bergamo beautifully blends its rich history with the vibrancy of contemporary Italian culture.
