Of all the gates in Florence's city walls, Porta San Frediano, founded in 1333 probably to a design by Andrea Pisano, is the largest and most imposing.
Scapitozzata (i.e. lowered) in the 16th century, it was covered by a gabled roof covered with tiles. The most interesting thing about it is the gate, composed of three different openings, the largest in the city and original to the period. Twelve metres high, it is entirely covered with nails to make it sturdier.
