Oratorio dei SS. Nazario e Celso

Halfway between Gudo and the hamlet of Progero, on a rocky spur, stands the oratory of Saints Nazario and Celso. The small 17th century building is preceded by a portico supported by pillars and has two bell towers. 
The apse has a stucco decoration with 17th century frescoes depicting the Adoration of the Magi and the Flight into Egypt.
