There are still solid traces which formed part of Florence’s old 14th Century fortifications. These are two walls spread out from the gate towards Piazza Tasso to the east and to the northwest along the Viali dei Colli. As with the Porta San Frediano, the two great, wooden bolted doors have been preserved. On the square opposite, towards the Poggio Imperiale, a statue by an important contemporary artist, Michelangelo Pistoletto, which depicts a woman cast in marble and entitled ‘Dietrofronte’, who appears to be leaving southwards from the city hindered by a heavy bundle on her head.
