The city walls of Florence, of which only a few sections remain, were organised as follows:
gates joined by walls, alternating with towers. The distance between the towers was 200 Florentine fathoms (about 100 metres).
The towers had both an aesthetic and security function. After the Porta San Frediano, proceeding towards the Arno, we find the towers of Verzaia and S. Rosa.
