    Guide

    Where the Star-Spangled Banner was born: a compact fort with sweeping harbor views and living history. It’s an easy win—flat paths, open lawns, and a visitor film that sets the scene in under 15 minutes.

    Start at the visitor center for your map, then follow the ramp to the east wall for the best harbor vantage. Time your visit for a flag raising or lowering—the ranger talk turns the place into a story you’ll remember.

    For a slower visit, circle the star-shaped ramparts clockwise and watch ships move in and out of the Patapsco.
