Terme di Nerone (L. Corevi, Comune di Pisa)Near the baths there is the Brunelleschi's Bastion: during the lordship of Cosimo the Elder de’ Medici some fortification projects were started, including the construction of the Parlascio Bastion,which takes its name from the oldest gate, dating back to 1157 and incorporated into the structure. It is a monumental gate, which still shows some decorations on the shelves supporting the large arch. In 1435, Filippo Brunelleschi built an internal counter door and rebuilt the fourteenth-century tower, which has now disappeared, but the entire bulwark was completed only in 1543 by architect Nanni Unghero, under the government of Cosimo I. The whole structure was later converted into ice-house and so it remained until the early twentieth century. During the war it served as a bomb shelter.
