Rude competition for the cathedral that is located in Piazza del Duomo but whose Maria Maggiore church and Cappella Colleoni deserve much more attention. Nevertheless, this cathedral dedicated to the saint of the city - Saint Alexander - is officially the most important since it was consecrated as a cathedral in 1697. The burial of the Saint Alexander was transferred from the church of San Vincenzo which was then cathedral of the city but then destroyed. The current construction was completed in 1693 in a baroque style in the interior and a neo-classical facade in white marble. There are a large number of chapels with among others paintings by Moroni and an imposing altar supported by six great angels. As elsewhere in Italy the baptistery is separate and is indeed placed closer to the Colleoni chapel but in a straight line opposite the cathedral. In particular, there is a modern chapel in honour of Pope John XXIII, born in a small village outside Bergamo and pope from 1958 to 1963. Entrance is free but it is closed from 12:30 to 15:00, so plan your visit. If we like the baroque style we will be satisfied!

The Duomo is the heart of the city, its spiritual center. The facade of Bergamo's main cathedral overlooks the oldest and most miniature square in the Duomo and is adjacent to the Palazzo della Ragione. It was once the site of a Roman forum, and since the 4th–5th centuries of the new era the first early Christian temple appears. Fragments of the frescoes of this early church can now be seen, thanks to archaeological excavations carried out in 2004-2012 and the Cathedral Museum established in their place. The church was originally dedicated to St. Vincenzo, but fate dictated that eventually another saint became the main patron of the city, St. Alexander of Bergam. It is his golden statue that crowns the dome of the cathedral. The temple has been rebuilt many times, so its facade is decorated in a neoclassical style, but the interior decoration of the church harmoniously combines not only classicism and baroque, but also modern decor, especially in the altar crypt of the bishops. Unique works of art adorn the cathedral: the bishop's pulpit in the altar, made in 1705 by the Bergamian carver Andrea Fantoni, the altar painting "The Execution of St. Giovanni Bishop of Bergam", by Giovanni Battista Tiepolo, 1745, paintings by Andrea Previtali and Giovanni Battista Moroni, among others.

Church (cathedral) dedicated to Sant'Alessandro Martire and cathedral of Bergamo. The church is very beautiful and bright, full of frescoes in soft colors and with many gold-colored finishes. Entrance is free unlike the neighboring church (Santa Maria Maggiore).

Bergamo Cathedral - Cattedrale di Sant'Alessandro Martire - Bergamo Cathedral - old historic and large cathedral located in Piazza Duomo. The church is beautifully decorated and a must-see here. The entrance was free. It took a long time to build up to its current state.

Worth a visit is the Cathedral of Bergamo alta next to the Basilica of Santa Maggiore. Free admission and already this thing is remarkable. Baroque interior. You can take pictures. Below there is a crypt where various bishops from Bergamo are buried. In one room instead there is the statue of St. John XXIII, the good pope. I recommend you come in.

It is not often you find two beautiful churches within a hundred feet of each other, but that is what you have in Alt Bergamo. This church is not as ornately decorated as the Basilica, but it is still impressive, especially the side chapels. The magnificent exterior is especially beautiful in the early morning light.
