Fort McHenry National Monument and Historic Shrine
After a 25-hour bombardment, soldiers at Fort McHenry raised a large American flag early on September 14, 1814. That flag, signaling British retreat, inspired Francis Scott Key to pen the words that became America's national anthem, The Star-Spangled Banner.
