Churches and places of worship Santuario Madonna della Cornabusa The Sanctuary of Madonna della Cornabusa is located at an altitude of about 700m, almost hidden in the stream, and looks like a cave. The name 'Cornabusa' comes from two words in Bergamo dialect: 'Corna' which means rock and 'Busa' which means hole. The sanctuary originated in the second half of 1400 when a deaf-mute girl from birth discovered the statue of the Virgin Mary in the cave during a thunderstorm.
