USS CONSTITUTION. The Constitution--called Old Ironsides because cannonballs could not penetrate her tough oak sides--was one of the first of the original six frigates that made up the U.S. Navy. A 44-gun frigate built at the Edmond Hartt Shipyard, Boston, MA, in 1797.
Today, more than 216 years later, she is still a commissioned U.S. Navy warship with a crew of naval officers and enlisted personnel. You can board the USS Constitution and learn more about the warship at the USS Constitution Museum. PIRATES As one of colonial Americaâs foremost seaports, Boston saw its share of piracy.
