Fort McHenry

Fort McHenry is located in Baltimore, Maryland. This low citadel overlooks the entrance to Baltimore harbor and it is where the Americans defended the city against British land and naval attack on September 13-14 in 1814. It was during this battle that Francis Scott Key began the draft to "The Star-Spangled Banner" after seeing the flag still flying after a day and night of bombardment.

The fort continued in active military service for nearly a century after the battle but changing technology eventually made it obsolete as a coastal defense system. Today the 43-acre fort is preserved as a national monument and historic shrine. The property is managed by the National Park Service and the flag is flown over the fort 24 hours a day.
