Casa Venier, Gothic palace in Campo Santa Maria Formosa, Venice, Italy

Casa Venier is a palace located on the northeastern side of Campo Santa Maria Formosa, displaying International Gothic features across its facade. The building showcases typical Venetian architectural details that define this central public square.

The palace was built in the 15th century and served as the home of the Venier family, an influential aristocratic line in Venice. From this residence came Sebastiano Venier, who later held significant positions within the city's republic.

The name comes from the Venier family, whose member Sebastiano Venier commanded the Venetian fleet at the Battle of Lepanto on 7 October 1571 and later became doge. A plaque placed on the facade by the Italian Navy on 7 October 1971, the battle's fourth centenary, marks the house; the ground floor now holds commercial premises.

The building can be viewed from the outside while visiting Campo Santa Maria Formosa and exploring the Castello district. The square itself is easy to reach on foot and connects to many other historical locations and pathways throughout the neighborhood.

The plaque on the facade was placed on 7 October 1971 by the Italian Navy, on the fourth centenary of Lepanto, and reads "Questa è la casa di Sebastiano Venier vincitore di Lepanto". The windows use a soft yellowish stone, probably from Vicenza, that has visibly eroded in the salt air.
