You have just witnessed the American flag still waving "by the dawn's early light" after
Discover Baltimore, the city that inspired the American national anthem, from Edgar Allan Poe's gravestones to the ramparts of Fort McHenry.
« By the dawn's early light »— Francis Scott Key, The Star-Spangled Banner, poem composed September 14, 1814, became US national anthem in 1931
Your journey begins at Westminster Hall and Burying Ground, founded in 1786. At the heart of this Gothic cemetery, built between 1807 and 1852, lies Edgar Allan Poe, whose remains were exhumed and reinterred in 1875. Over 1,400 notable figures, including several signers of the Maryland Declaration of Independence, found their final resting place here. This site serves as a gateway to Baltimore's history, connecting literary figures with the founding fathers of the region. The main building, with its 60-foot-high central tower, prepares you for the historical narratives that punctuate the route.
A short walk away, the Edgar Allan Poe House and Museum, a small federal-style dwelling built around 1830, reveals the writer's daily life between 1833 and 1835. It was here that Poe wrote several major poems and tales, and where the inspiration for 'The Raven' reportedly took shape. This site, though focused on the author's life, highlights Baltimore's intellectual vibrancy in the 19th century, a period when the city forged a strong cultural identity alongside its military history. The connection to Westminster Hall creates a unique literary journey in Maryland.
The route then leads you to the Washington Monument, the first monument dedicated to George Washington in the United States, erected between 1815 and 1829. Designed by Robert Mills, this 178-foot (54-meter) obelisk dominates Mount Vernon Place, a historic circular square. Its construction immediately after the War of 1812 and the Battle of Baltimore symbolizes national pride and unity after the confrontation with British forces. This monument serves as a reminder of American independence, a central theme of the Battle of Baltimore and the American national anthem.
Continue to the Star-Spangled Banner Flag House, the historic home of Mary Pickersgill, the seamstress who in 1813 crafted the 30x42-foot flag that inspired the national anthem. This house, built in 1793 and opened as a museum since 1927, is a direct testament to the event. It directly links to the Battle of Baltimore of 1814 and the Inner Harbor, where Francis Scott Key witnessed the bombardment of Fort McHenry. Visiting this site is an immersion into the creation of a national symbol, reinforcing the context of your investigation.
Your exploration culminates at Fort McHenry National Monument and Historic Shrine. This fort, built in 1798 and bombarded by the British on September 13-14, 1814, is where Francis Scott Key composed 'The Star-Spangled Banner'. Administered by the National Park Service since 1925, it celebrates Defenders Day annually. The panoramic view from Federal Hill Park over the Inner Harbor, a deep natural port redeveloped between 1970 and 1980, allows you to grasp the extent of military operations. The Fells Point neighborhood, founded in 1730 with its 1786 market house and colonial homes, completes this historical picture, showing how Baltimore, a city in Maryland, survived and thrived after these decisive events of the Battle of Baltimore.
