Fort McHenry National Monument

O! say can you see,... by the dawn's early light, a large red, white and blue banner? Whose broad stripes and bright stars . . . were so gallantly streaming! over the star-shaped Fort McHenry during the Battle of Baltimore, September 13-14, 1814. The valiant defense of the fort inspired Francis Scott Key to write "The Star-Spangled Banner."

Fort McHenry, in Baltimore, Maryland, is a star-shaped fort best known for its role in the War of 1812, when it successfully defended Baltimore Harbor from an attack by the British navy in Chesapeake Bay September 13-14, 1814. It was during the bombardment of the fort that Francis Scott Key was inspired to write "The Star-Spangled Banner," the poem that would eventually be set to the tune of "To Anacreon in Heaven" and become the national anthem of the United States.
