“Because of movements in the flooded subsoil many old Florentine buildings became more or less unstable, but fortunately the structure of no major monuments is threatened, having survived, we must remember, a flood every century. Almost all the important churches and palaces in the center of the city, including the Pazzi Chapel, suffered damage to roof, walls, and pavements. The excavations undertaken with CRIA funds to examine the footing of the columns of S. Croce has led to the uncovering of the walls and foundations of the entire original basilica.”
