Tower, heraldic symbol of the coat of arms of Clement XIII

The central window of the right wall, reopened in 2005 together with the others, has a gold decoration which, made on the visible side when the doors were open, remained protected and hidden for almost two centuries. It is now intact and bright and shows the heraldic symbols of the tower and the crowned double-headed eagle present in the coat of arms of Pope Clement XIII Rezzonico, who commissioned these decorations in 1763 to the painter Giovanni Angeloni.
