Georgetown is a neighborhood located in the Northwest quadrant of Washington, D.C., along the Potomac River waterfront. Founded in 1751, the city of Georgetown substantially predated the establishment of the city of Washington and the District of Columbia. Georgetown retained its separate municipal status until 1871, when it was assimilated into the city of Washington. Today, the primary commercial corridors of Georgetown are M Street and Wisconsin Avenue, which contain high-end shops, bars, and restaurants.
