Chigi is one of the most beautiful towers in San Gimignano and was built in 1280 by the Useppi family.
One of its distinctive features is that the entrance door is on the first floor. In fact, due to the fights between families in the city, in order to sleep peacefully, the entrance was placed on the first floor and, during the day, a staircase was lowered, to allow those who lived there to go down to the street. The ladder was then pulled up during the night. On the second floor, the window is a narrow slit, with an elongated arch resting on corbels. The upper part has two identical mullioned windows on the first two floors, while the top floor has no opening.
