USS Constitution
Affectionately known as "Old Ironsides," the USS Constitution rides proudly at anchor in her berth at the Charlestown Navy Yard. The oldest commissioned ship in the U.S. fleet is a battlewagon of the old school, of the days of "wooden ships and iron men"—when she and her crew of 200 succeeded at the perilous task of asserting the sovereignty of an improbable new nation. Every July 4, she's towed out for a celebratory turnabout in Boston Harbor, where her keel was laid in 1797.
The venerable craft has narrowly escaped the scrap heap several times in her long history. She was launched on October 21, 1797, as part of the nation's fledgling navy. Her hull was made of live oak, the toughest wood grown in North America; her bottom was sheathed in copper, provided by Paul Revere at a nominal cost. Her principal service was during Thomas Jefferson's campaign against the Barbary pirates, off the coast of North Africa, and in the War of 1812. In 42 engagements her record was 42–0.
The nickname "Old Ironsides" was acquired during the War of 1812, when shots from the British warship Guerrière appeared to bounce off her hull. Talk of scrapping the ship began as early as 1830, but she was saved by a public campaign sparked by Oliver Wendell Holmes's poem "Old Ironsides." She underwent a major restoration in the early 1990s. Today she continues, the oldest commissioned warship afloat in the world, to be a part of the U.S. Navy. In 2015, she was dry docked for a 26-month restoration that included replacement of select hull planks, the 1995 copper sheathing, and deck beams, returning to the water in 2017.
The navy personnel who look after the Constitution maintain a 24-hour watch. Instead of taking the T, you can get closer to the ship by taking MBTA Bus 93 to Chelsea Street from Haymarket. Or you can take the Boston Harbor Cruise water shuttle from Long Wharf to Pier 4. This is Freedom Trail stop 15.
