Baltimore, Maryland

A portion of the Mason-Dixon line
catalog record

Baltimore was established as a city in 1729, becoming the most important port in the United States until the Erie Canal steered commerce toward New York City.

Situated below the Mason-Dixon line, Baltimore has the flavor of the urban north and southern warmth. It is an important shipbuilding center, where many 19th-century clipper ships were built. During the American Revolution, the Continental Congress met in Baltimore, after English soldiers took the national capital, Philadelphia. Fort McHenry, just southeast of the city, was built around 1790-1800 to defend the harbor. It was under siege during 1814 by the British, and that battle inspired Francis Scott Key to write “The Star-Spangled Banner.”
