Chiesa della Natività di Maria

Few churches tell of such a long stratification. On the site, perhaps already in the 1st century and more probably in the 4th, stood a Roman watchtower; the excavations found the remains of another building dating to within the 6th century, and of an early church dating to within the 10th, oriented to the east, with the graveyard at the back.

The medieval structure, oriented to the south, was built between the 11th and the 13th century, incorporating the pre-existing chapel; a plebano of Varollo appears in 1214. After the enlargement of the early 14th century began the season of decorations: Madonna with Child, Saint Mary Magdalene, Saint George and the princess, Saint Christopher, a Deposition, and some frescoes attributable to the Bergamasque masters linked to the Baschenis, the same who worked in the chapel of Castel Valer.

The oldest bell was cast in 1463. Between 1528 and 1537, at the wish of the pievano Biagio Aliprandini, part of the building was demolished and rebuilt larger and taller.
