Palace Smith Mangilli Valmarana, Neoclassical palace in Cannaregio, Venice, Italy.

Palace Smith Mangilli Valmarana is a three-story building along the Grand Canal featuring neoclassical design. Its facade displays rectangular windows framed by Corinthian pilasters and half-columns, with a central water entrance that provides direct access from the canal.

British Consul Joseph Smith purchased the building in 1740 and hired architect Antonio Visentini to redesign its facade, transforming it from a Gothic-Byzantine structure between 1743 and 1751. This renovation created the neoclassical appearance visitors see today.

The palace is named for Joseph Smith, the English consul who bought it in 1740 and acted as Canaletto's agent selling his paintings to British buyers. In 1784 it passed to Count Giuseppe Mangilli, then to the Valmarana family of Vicenza, whose name completes the present title.

The palace faces the Grand Canal at the mouth of the Rio dei Santi Apostoli in Cannaregio, next to Palazzo Michiel del Brusà. Its water portal opens directly onto the canal, so it is seen from the water rather than from a land entrance. The sources do not mention public opening hours or interior visits.

The facade Antonio Visentini designed in 1743 only reached the level of today's first noble floor; the upper floors were added in 1784 by Count Giuseppe Mangilli. The building stands where the rio dei Santi Apostoli meets the Grand Canal, next to Palazzo Michiel del Brusà.
