In the early 15th century, it was a place for ships from the east to dock to pay taxes to customs. After many renovations, the customs minarets were built in 1677, and a small tower was erected on the roof. On the tower were two statues of slaves, holding a giant gilded skyball, a sculpture of the goddess of luck (Chucepe Booni in the 17th century), who stood with one foot and could turn with the wind to indicate that people would follow things, both at sea and in their careers Change and change. Very characteristic architecture, one of the hallmarks of Venice.
