Solo, Basilica di Santa Maria della Salute is an easy yes.
Longhena's octagonal white domed Salute is the silhouette that crowns every Grand Canal photo, built in thanks for deliverance from plague; inside, the sacristy holds Titian and Tintoretto canvases. Standing on its steps where the canal meets the basin is one of Venice's free pleasures. The catch: the main church is free but plain-ish for its fame, with the real art behind a small-fee sacristy door.
