The Porta San Frediano was the westernmost gate in the 13th-century walls of the Oltrarno section of Florence, region of Tuscany, Italy.
This ancient gate is attributed to the architect Andrea Pisano, and is named after the nearby church of San Frediano, which was rebuilt as the church of San Frediano in Cestello.
This vision was interpreted as a premonition that the Florentines would defeat the Pisan army at the Battle of Cascina.
[1] Through this gate, King Charles VIII of France entered Florence.
[2] A depiction of the gate in c. 1494 can be seen in a painting by Filippino Lippi, namely the Madonna and Child with Saint John among Saints Martin of Tours and Catherine of Alexandria found in the Nerli Chapel of the church of Santo Spirito, Florence.
