The Ca' Pesaro is a Baroque marble palace turned art museum, facing the Grand Canal of Venice, Italy. Today it is one of the 11 museums run by the Fondazione Musei Civici di Venezia system. The building was originally designed by Baldassarre Longhena in the mid-17th century, the construction was completed by Gian Antonio Gaspari in 1710. As at Longhena's Ca' Rezzonico, a double order of colossal columns and colonnettes flanking arch-headed windows, reinterpreting a motif of Jacopo Sansovino, Longhena creates the impression of double loggias extending across the main Grand Canal frontage, above a boldly rusticated basement.
