Fort McHenry

Fort McHenry is a brick waterfront fortification in pentagonal form with ramparts, cannons, barracks, and exhibits housed in multiple buildings within the walls. The complex preserves the original layout of defenses visible from the water.

During the War of 1812, this fortification withstood a 25-hour British naval bombardment on September 13 and 14 in 1814, successfully protecting Baltimore harbor. The defense prevented British forces from advancing into the city.

Francis Scott Key wrote the words to the national anthem after watching the American flag continue flying over this fortification following the battle. The text came to him while he observed from a ship offshore, seeing the flag still in place.

Visitors can explore the grounds daily from 8:00 AM to 5:00 PM, starting at the visitor center where orientation films present the background. The walk along the ramparts is open and offers views of the harbor.

The original garrison flag measured about 30 by 42 feet (9 by 13 meters) and required multiple people to raise and lower it. Today it rests in the Museum of American History in Washington, showing clear signs of age.
