The USS Constitution is the world's oldest commissioned warship afloat and America’s Ship of State — a wooden-hulled, three-masted frigate (a type of heavy warship) of the United States Navy, named by President George Washington after the Constitution of the United States. Launched in 1797, the USS Constitution was one of six original frigates that were authorized for construction by the Naval Act of 1794 and the third one ever built.
The USS Constitution is located inside Boston National Historical Park as part of the Charlestown Navy Yard and part of Boston's Freedom Trail, a 2.5-mile path through downtown Boston that passes by 16 locations that are significant to the history of the United States.
This 45-minute journey visits “Old Ironsides,” with the option to disembark for a tour of the famous ship and USS Constitution Museum. Also on the tour, see Bunker Hill Monument, which was built to commemorate the Battle of Bunker Hill, the first major conflict between British and Patriot forces in the American Revolutionary War; the Boston Tea Party Ships and Museum, a floating history museum with live reenactments, multimedia exhibits and, of course, a tearoom; and Old North Church, Boston's most-visited historical site, where the famous "One if by land, and two if by sea" signal is said to have been sent.
