The Ca' Pesaro is a Baroque marble palace facing the Grand Canal of Venice, Italy. Originally designed by Baldassarre Longhena in 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.
