USS Constitution. Launched in Boston in 1797, the oldest commissioned warship afloat earned her nickname Old Ironsides during the War of 1812 when she fought the British frigate HMS Guerriere. During this historic battle, cannonballs fired at USS Constitution appeared to bounce off, causing one of her crew to remark that her sides were made of iron.
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.
