At Charlestown Navy Yard, USS Constitution is a wooden, three-masted frigate launched in 1797 and still afloat as the U.S. Navy’s oldest commissioned warship. Known as “Old Ironsides,” it earned the nickname during the War of 1812, when its thick hull appeared to withstand British cannon fire. You can board the ship, hear Navy sailors explain its history and look across its upper decks. The USS Constitution Museum, just across the pier, adds exhibits about the vessel and life at sea. Admission to the ship is free.
A frigate with a long service life
USS Constitution was one of six frigates commissioned for the early U.S. Navy. President George Washington chose its name, and the ship was launched in Boston in 1797. Its three masts and wooden hull remain part of the vessel you see at Charlestown Navy Yard today.
The nickname “Old Ironsides” dates to the War of 1812. During a fight with the British frigate HMS Guerriere, the ship’s thick hull appeared to turn aside cannonballs. The name stuck, and the ship became known for its wartime record. It later served in the Civil War, before its role changed from active service to ceremonial duties and public visits.
What you can see aboard
The visit takes you onto the ship’s upper decks, where sailors explain its construction, weapons and history at sea. The route also gives you a close look at the scale of the frigate, from its masts above to the working spaces below. Narrow steps lead down to lower levels, but not every deck is open to the public. Access can vary, so plan to see the areas available on the day rather than expecting to tour the entire ship.
Guided talks are led by active-duty Navy personnel. Their explanations connect the ship’s equipment and layout with life aboard an early naval vessel. If you want more context as you walk around, listen for the crew’s talks before setting off to explore independently.
The museum across the pier
The USS Constitution Museum is in Building 22, across the pier from the ship. Its exhibits add detail about the vessel’s construction, maritime history and restoration, as well as everyday life aboard a naval ship two centuries ago. Interactive displays make it a useful companion stop for families and anyone who wants more than the ship tour alone.
The ship and museum have separate visits and admission arrangements. Boarding the ship is free, while the museum uses a suggested admission contribution. Check the museum’s current details before you go if you want to plan that part of the visit.
Planning your visit
The Navy Yard is part of Boston’s Freedom Trail, and the ship is a natural stop when exploring historic sites in Charlestown. You can also visit it as a destination on its own, then continue to the nearby USS Constitution Museum.
Allow time for the security check before boarding. Adults need photo ID, and a queue may form at the ship. Wear shoes that are easy to walk in on steps; some passages are low, so be ready to duck. The ship’s public access and tour schedule can change, so check the official USS Constitution site before setting out.
