Palazzo Bollani Erizzo, 13th-century palace on the Grand Canal in Cannaregio, Venice, Italy

Palazzo Bollani Erizzo is a 13th-century Venetian palace on the Grand Canal in the Cannaregio district, built wall to wall with Palazzo Dolfin. Its narrow facade has two noble floors, each with a three-part mullioned window with large arches on columns. The ground floor has an arched portal moved to the left, flanked by two small rectangular windows on the right, with Istrian stone details on all arched openings and the lower ground floor. The top floor has four rectangular windows with a frontal balcony: the two middle ones share an iron-railed balcony, while the two lateral windows each have their own.

Built in the 13th century along the Grand Canal in Cannaregio, the palace was the residence of poet Pietro Aretino in the 16th century. In the early 19th century it was bought by the Levi family; the banker Cesare Levi acquired it in 1888 for the marriage of his daughter Bice to Mandolino Oscar Finzi. After World War One the engineer Gino Vittorio Ravà lived there, and during World War Two the poet Filippo Tommaso Marinetti rented it briefly, founding the futurist association Cannaregio 5662 there in 1944.

The palace takes its name from the Bolani and Erizzo families, though the sources record no Erizzo paintings inside. Its cultural mark comes from its residents: the poet Pietro Aretino lived here in the 16th century, and in 1944 Filippo Tommaso Marinetti founded the futurist association Cannaregio 5662 within its walls.

This palace is accessible by water route like all Grand Canal buildings in Venice, allowing visitors to view the architecture from boats and gondolas. The facade is best appreciated from the canal itself, where its proportions and stone details become most apparent.

Engineer Gino Vittorio Ravà developed the hydraulic jack restoration method while residing in this palazzo. His innovation for preserving buildings was conceived and tested within the walls of this very structure.
