On the Grand Canal, in the Cannaregio sestiere (district — Venice has six) between Palazzo Querini Papozze and Palazzo Gritti, the majestic 17th-century facade of Palazzo Correr Contarini Zorzi is known to all of Venice as Ca’ dei Cuori, the ’House of Hearts’: the nickname comes from the heart-shaped wrought-iron coats of arms adorning the two water portals and the courtyard.
