The Palazzo Contarini del Bovolo (also called the Palazzo Contarini Minelli dal Bovolo) is a small palazzo in Venice, Italy, best known for its external multi-arch spiral staircase known as the Scala Contarini del Bovolo (literally, “of the snail”).

The palazzo is located in a small, less-travelled calle (street) near Campo Manin, about half-way between Campo San Bartolo, at the foot of the Rialto, and Campo Santo Stefano.

The staircase leads to an arcade, providing an impressive view of the city roof-tops.
