USS Constitution

Old Ironsides is the world's oldest commissioned warship still afloat, a three-masted 1797 frigate you can board for free in the Charlestown Navy Yard. Active-duty sailors give tours and the adjacent museum fills in the history. You'll need a photo ID for the security check and the ship occasionally closes for maintenance.

Key facts

Frequently asked questions

How do I get there?

The most fun way is the MBTA Inner Harbor ferry from Long Wharf downtown straight to the Navy Yard. Otherwise take the Orange Line to Community College and walk about 15 minutes, or arrive via the Freedom Trail.

What days and hours is it open?

Generally Wednesday through Sunday, roughly 10am to 6pm, closed Monday and Tuesday, with seasonal variation. Access can change with Navy operations, so check the navy.mil USS Constitution page the day you plan to go.

Is there security screening?

Yes, because it's on an active naval base, adults 18+ must show government-issued photo ID and go through a screening similar to a courthouse. Leave large bags behind and allow a few extra minutes.

Can you go below deck?

Yes, tours typically take you onto the top decks and often below to see the gun deck and living quarters, depending on the day and Navy schedule. Ceilings are low, so mind your head.

Is it good for kids?

Great for kids, especially paired with the hands-on museum where they can climb into a hammock and haul a sail. The real sailors in uniform aboard the ship make it memorable. Strollers are tricky on the ship's ladders.

What's the difference between the ship and the museum?

The ship itself is free and run by the Navy. The USS Constitution Museum nearby is a separate nonprofit with a suggested donation, full of interactive exhibits and great for kids. Do both; they complement each other.

Why is it called 'Old Ironsides'?

During the War of 1812, British cannonballs appeared to bounce off its thick live-oak hull, and a sailor supposedly shouted that her sides were made of iron. The nickname stuck. It never lost a battle.

Is USS Constitution free to visit?

Yes, boarding the ship is free. It's an active US Navy vessel crewed by real sailors who guide you aboard. Adults need to show a valid photo ID and pass a quick security screening, since it's on a military base.
