Bergamo Cathedral, also known as the Cathedral of Saint Alexander, is the principal place of worship in the city and serves as the seat of the Bishop of Bergamo. The current structure was primarily constructed between the 15th and 17th centuries, though excavations beneath the floor have revealed the remains of an early medieval paleochristian basilica. The interior features a significant collection of Baroque paintings, notably works by artists such as Andrea Previtali and Giovan Battista Moroni. Its neoclassical facade, completed in the 19th century, dominates the Piazza Duomo in the historic Città Alta. The interior design underwent major modifications in the 17th century to align with the aesthetic requirements of the Counter-Reformation. The cathedral houses the relics of Saint Alexander, the patron saint of the city. Beneath the cathedral, an archaeological path allows visitors to view the structural layers of previous religious buildings on the site. It is integrated into the larger religious complex of the square, which includes the Colleoni Chapel and the Basilica of Santa Maria Maggiore.
The view of the facade from the center of Piazza Duomo provides the best perspective of its architectural symmetry.
Visit the underground archaeological site to see the foundational layers of the previous cathedrals.
Look for the wooden choir stalls in the apse, which demonstrate intricate craftsmanship.
Spend time in the adjacent Piazza Duomo, as the cathedral is part of a dense historical enclave.
Avoid visiting during active liturgical services, as tourism is discouraged while mass is in progress.
The archaeological area may have different operating hours than the main nave; check for mid-day closures.
Shoulders and knees must be covered; remove hats upon entry; maintain a quiet voice.
