Slices of American history are around every corner in Baltimore. Maryland's largest city is a gritty old seaport town that's perhaps most famous as the site of Fort McHenry, where, at the height of the War of 1812, the sight of a tattered but defiant American flag flying over the harbor, despite a furious British bombardment, inspired Francis Scott Key to write the poem that was later adapted into the U.S. national anthem "Star-Spangled Banner". Nowadays, Baltimore's nonstop nightlife, temperate climate, tradition of hospitality (they don't call this place "Charm City" for nothing), and cultural attractions — not to mention its prime location on the juncture of Chesapeake Bay — made it one of the major tourist destinations of the Mid-Atlantic region.
