This is where Catherine, at the age of just seven, had her first vision. While she was walking home from Fontebranda with her brother Stefano, she saw Jesus wearing papal robes seated on a throne above the Basilica of San Domenico, which looms large in view of the street. With Him were Saints Peter and Paul, the princes of the apostles, and Saint John the Evangelist.

This vision left a deep mark . . .
