National Park Service, Maryland.
For three years the young United States was embroiled in the War of 1812 and the Chesapeake Bay region felt the brunt of it, choked by shipping blockades and ravaged by enemy raids. Through sites and landscapes in Virginia, the District of Columbia, and Maryland, the Trail tells the stories of the events, people, and places that led to the birth of the U.S. national anthem.
The Trail's headquarters is at Fort McHenry National Monument and Historic Shrine. The park is three miles southeast of the Baltimore Inner Harbor and just off I-95. Follow the brown Fort McHenry directional signs along all major routes to the park. From I-95 northbound, take Exit 55 Key Highway and follow Fort McHenry signs.
