Georgetown, located in Northwest Washington DC, situated along the Potomac River waterfront was founded in 1751. The port of Georgetown predated the establishment of the federal district and the city of Washington by 40 years. Georgetown remained a separate municipality until 1871, when the United States Congress created a new consolidated government for the whole 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 the home to the main campus of Georgetown University and numerous other landmarks such as the Volta Bureau and the Old stone house, the oldest unchanged building of Washington. The embassies of France, Mongolia Sweden Thailand and Ukraine are also located in Georgetown. Today Georgetown is one of the most affluent neighborhoods in Washington and home to many of the city's politicians and lobbyists. High-end developments and gentrification have revitalized Georgetown formerly blighted industrial waterfront. Much of Georgetown is surrounded by parkland and green space that serves as buffers from development and adjacent neighborhoods and provides recreation. .Among these areas are, Rock Creek Park, the Oak Hill cemetery, Montrose Park and Dumbarton Oaks.
