In the square, there is a monument to Dante Alighieri sculpted by Enrico Pazzi in 1865 to celebrate his 600th anniversary. On the opposite side of the square, surrounded by noble palaces, there is a fountain. In the sacristy, there is a restored crucifix painted by Cimabue around 1272, 4.48 meters high. It was heavily damaged by the flood of 1965.
In this square, traditionally, the Florentine historic football or football in costume (herpastum in Latin) was played. Even today, matches are played in June in honor of the patron saint, St. John, in Piazza Santa Croce.
