    Explore Baltimore/Washington

    Like many cities and towns on the eastern seaboard, Baltimore is steeped in history—much of which is from the vibrant communities that have called it their home generation after generation. These communities built Baltimore into a city of neighborhoods, featuring 72 official historical areas, each of which is waiting for you to come explore. Hop on the MTA Maryland or the Charm City Circulator to get started.

    If you find yourself overcome with American pride during your visit, that may be thanks to the city’s fame as the birthplace of the “Star-Spangled Banner.” A trip to Fort McHenry, where Francis Scott Key was so inspired, may be in order. Make a day of it by starting at Baltimore Harbor then taking the water taxi to the landmark. There are lots of landmarks to discover around the city—it is called Monument City, after all—and many museums too.
