Only yards away from "Old Ironsides," the USS Constitution Museum is a "must see" for everyone visiting Boston, where interactive galleries take adults, families and children of all ages on a 200-year voyage. Here, visitors can learn how a wooden hull helped the ship earn the nickname “Old Ironsides;” discover how "Old Ironsides" has remained undefeated since being launched in 1797; find out how school children contributed pennies to help save "Old Ironsides;" and see how sailors ate a diet of hardtack and grog, and climbed masts 200 feet in the air.
