Of Boston's many attractions, perhaps its most beloved isn't in the city itself, but floating on the water of Boston Harbor. The USS Constitution is an original three-masted heavy frigate of the U.S. Navy, and it has been in service for more than 200 years, having been originally launched in 1797. Today, it's the oldest commissioned ship afloat anywhere and a "ship of state," intended to represent United States naval traditions to the world. To that end, visitors can board and tour this remarkable vessel that served the nation through the first Barbary War, the War of 1812, the Civil War, and countless other missions. Anybody who has ever dreamed of taking off on a sailing ship to see the world will appreciate the many fine details of "Old Ironsides," from its intricate sails and rigging to its expansive wooden decks, which - true to history - require constant swabbing. In addition to the ship, there's also a museum nearby on dry land with exhibits describing the long, honorable life of this majestic sailing ship. Guests at the nearby Westin Boston Waterfront or any of Starwood's Boston properties might appreciate a tour or turnaround cruise on the floating piece of American history.
