Where on earth is the metro a primary reason for visiting? Nowhere. Usually it's the primary reason

Venice is divided into six districts called "Sistieri" in Italian; that word will come in handy when you're floating hither and yon. They are Cannaregio, San Polo, Dorsoduro, Santa Croce, San Marco, and Castello.
Beyond these, there's Lido and Mestre. Lido is a sandbar to the east of Venice with 20,000 permanent residents and 65 tranzillion summer people. In the beginning of the 12th century, thousands of Crusaders were stuck here in Lido when they could not afford to pay transport rates for Venetian ships! See, location really IS everything.
On the west side of the Lagoon is Mestre, which has the airport, the buses, the traffic and basically everything else from modern life that you come to Venice to ignore. To be fair, for centuries now Mestre has borne the brunt of the international shipping traffic coming into Porto Marghera, while "Venice" takes all the credit. Typical older sibling.
How did it get here? Venice used its location at the top of the Adriatic to become a massive naval and commercial power. By the end of the thirteenth century, trading among the Byzantine Empire and the Muslim countries to the south had made Venice the wealthiest city in Europe.
Venice declined in stature from the 15th century. First they lost a war against the Ottoman Empire and then lost a lot of business when a sea route to India bypassed their port. The Plague came in next and wiped out a third of the citizens

Real quick -- opera was an Italian invention for combining Greek tragedies with music, theater be a travel agent and spectacle. be a travel agent It broke out of private royal courts and became a public event as of 1637, supported by a season of ticket sales before Lent. Hence opera season.
Pow, zing, wow and instant popularity. Masks were permitted to be worn in public, European dignitaries arrived from everywhere, and this was THE PLACE to be. I mean, like, imagine Louis XIV getting up on stage to prance while the orchestra freaks out and plays the ritornello a few more times until he wants to sit down again. (Orchestras don't really improvise so well).
Ever been to the movies? Thank Venice. In fact, to this day a vestige of the operatic tradition remains -- Lido hosts the Venice Film Festival in September of every year. Hint hint, late summer visit, hint hint.
Now it's time to look at that map and start cheering because you can take a BOAT to and from the airport!! Traffic jams do not exist on boats. Maybe some kind of docking delay once in a while, but who's going to complain about that?
Where on earth is the metro a primary reason for visiting? Nowhere. Usually it's the primary reason for LEAVING. Let me wipe the sweat of ugly metro-memories from my brow before we go on to this placid paradise.
Rialto Bridge is one of the three bridges that cross the Grand Canal - the others two are the Accademia Bridge and the Scalzi Bridge. It is dated 1591, a masterpiece of Antonio Da Ponte, after a long story of failures, disappointments, and falling wooden bridges...

Venice has a rich history and it's all slowly sinking into the sea. By pumping water for industrial uses, Venetians unintentionally removed some of the city's geological foundation. Soft mud, islands and tides did the rest.
