Fort McHenry
Fort McHenry, in Baltimore, Maryland, is a historical American
coastal 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 from the Chesapeake Bay September 13β14, 1814. It was first built in 1798 and was used continuously by U.S. armed forces through World War I and by the Coast Guard in World War II. It was
designated a national park in 1925, and in 1939 was redesignated a
"National Monument and Historic Shrine,"
During the War of 1812
a storm flag (17 by 25 feet (5.2 m Γ 7.6 m)) was flown over Fort McHenry during the bombardment. It was replaced early on the morning of September 14, 1814 with a larger garrison flag (30 by 42 feet (9.1 m Γ 12.8 m)). The larger flag signaled American victory over the British in the Battle of Baltimore. The sight of the ensign inspired
Francis Scott Key to write the poem
"Defence of Fort M'Henry" that was later set to the tune To Anacreon in Heaven and become known as the Star Spangled Banner, the national anthem of the United States.
