Porta San Giovanni
An imposing complex consisting of an access arch to the center and buildings that had the specific function of housing the house of the Bargello (captain of the people) and the guard.
It is to be considered perhaps the most interesting part of the walls as it preserves unchanged many elements of defense including the so-called “bianchetta”, the small door to the left of the arch that allowed access to the center during the night or during periods of siege. There are also the housing of the beams that are part of the drawbridge, the hinges of the doors and the holes, where the beams were inserted to bar the door. Inside the arch there was definitely a wooden scaffold that was used to reach the different vents. On the left wall of the entrance, in a niche carved from a fire vent, there is an eighteenth-century image of the Madonna, in papier-mâché, which enjoys a particular popular veneration. Entering you pass an ogival arch, where there is a crack: here flowed an iron gate, extreme defense against the besiegers. Turning towards the Pozzo del Bargello you can reach the terrace above the arch, where you can admire a landscape of both the center and the countryside. Also here are typical elements of military architecture of the fourteenth and fifteenth, such as darters, arquebusiers, brackets, plumbers and battlements. Probably the large terrace was covered by a roof to allow defense during adverse weather. In November 1987, Prince Charles of England spent a long time on the terrace painting a glimpse of the old town.
