The Palazzo Vendramin-Calergi on the Grand Canal. The Wagners took up residence in the mezzanine apartment in September 1882; the room where the composer died, on Feb. 13, 1883, is on the right side. The building is now occupied by the Casino di Venezia — "An Infinite Emotion" is their slogan — but the Associazione Richard Wagner di Venezia maintains an excellent small archive in Wagner's private rooms.
