Designation: National Monument and Historic Shrine
Location: Maryland
by the dawn's early light, a large red, white and blue banner? Whose broad stripes and bright stars... were so gallantly streaming...over Fort McHenry! The valiant defense of the fort during the Battle of Baltimore on September 13-14, 1814 inspired Francis Scott Key to write the words that became the U.S. national anthem. The fort's history holds many other stories too, from the Civil War to WWII.
Temperatures and weather in the spring and fall months tend to be mild. Ice, snow, and freezing temperatures can occur during winter. Extreme heat can occur during the summer months. Inclement weather may impact park hours of operation year round. Refer to the park alerts or call ahead to confirm operating hours.
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.

Fort McHenry is the first site to receive a presidential proclimation requiring that the site fly a flag 24/7, 365 days a year. Join park staff in the mornings or evenings as we change out our flags for the day and learn about the flag's significance to the park's history. Flag change programs occure daily. In the mornings the park raises a larger replica of a historic flag and in the evenings an overnight all-weather flag is raised over the fort.
*Flag changes are weather dependent.
