The Snail's Staircase
Inside the tower is the staircase of the late-Gothic Palazzo Contarini del Bovolo. Although external staircases were the norm in Venetian palazzi of the 14th and 15th centuries, this staircase stood out from the crowd in terms of its size and shape.
To distinguish it from the many other palaces in the city belonging to the Contarini family, this palace was named 'del Bovolo', from the Venetian word for snail.
The staircase is connected to the main structure of the palazzo by a delightful side addition made up of four loggias. The design is attributed to Giovanni Candi, who died in 1506.
