Santa Maria della Salute
This flamboyant church at the mouth of the Grand Canal—all round exterior, vast dome, and scalloped flourishes around the roof—is one of Venice's landmarks. Opened in 1681 to celebrate the city's release from the plague, it's been immortalized in the works of Canaletto, Turner, and John Singer Sargent. Entry is free—unusual for Venetian churches—as are the regular organ recitals. Don't miss the sacristy, which has works by Titian and Tintoretto, and the Pinacoteca Manfrediana art gallery next door. Although there are no big hitters, it's a lovely little museum.
