Fort McHenry National Monument and Historic Shrine
Fort McHenry occupies a strategic position along the Patapsco River protecting the entrance to Baltimore Harbor, reflecting the importance of coastal fortifications in the early defensive network of the United States. Constructed beginning in 1798 as part of the nation’s first system of seacoast defenses, the star-shaped masonry fort illustrates late eighteenth-century military engineering designed to defend major port cities. Its geographic position within the Chesapeake Bay made Baltimore a key strategic objective during the War of 1812.
The fort became nationally significant during the Battle of Baltimore in September 1814, when American forces withstood a twenty-five hour naval bombardment by the British Royal Navy. The continued presence of the American flag above the fort inspired Francis Scott Key to compose the poem that later became “The Star-Spangled Banner,” linking the site permanently with the development of national symbolism. The preserved fortifications, ramparts, and surrounding landscape demonstrate how military architecture shaped the defense of early American cities during a period of geopolitical uncertainty.
Fort McHenry contributes to understanding how places associated with national conflict can become enduring symbols of identity and collective memory. The site reflects the intersection of geography, military history, and cultural symbolism within the Chesapeake region. Its preservation as the only National Monument and Historic Shrine in the National Park System reinforces the continuing interpretive importance of the War of 1812 in shaping the early republic.
We all know the National Anthem…here is the fort that was defended and gave Francis Scott Key the idea for the Star Spangled Banner…from the 1814 Battle of Baltimore.
