Portaccia di Istia
The door was built in the twelfth century, simultaneously with the tower. Over the centuries, the structure underwent several changes that, during the Sienese occupation, added the upper arches. With the spread of malaria, and the abandonment of the territory, they determined the degradation of the walls and the door itself. The door is currently in a poor state of preservation.
