Georgetown is a neighborhoo 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. By 1776, Georgetown was one of the largest cities in Maryland, and retained its separate municipal status until 1871, when it was assimilated into the District of Columbia. Today, the primary commercial corridors of Georgetown are M Street and Wisconsin Avenue, which contain high-end shops, bars, and restaurants. Georgetown is home to the main campus of Georgetown University and the Old Stone House, the oldest standing building in Washington. The embassies of France, Mongolia, Sweden, Thailand, and Ukraine are located in Georgetown.
