We can read the history of Florence walking through its streets and observing the many historic buildings. We walk beside tower-houses and we are back in the 12th century town.
City life was not yet regulated by laws. On the war-ridden streets, muscular belligerent factions battled for territorial dominion. Democracy was unidentified.
Tall turreted buildings shielded the factions and their families.
The Castagna tower-house, near the so-called house of Dante is the best discernible building.
There are other tower-houses now inhabited while many were lost from sight, smothered by subsequent constructions.
