Foggy Bottom is one of the oldest late 18th- and 19th-century neighborhoods in Washington, D.C. Foggy Bottom is west of the White House and downtown Washington, in the Northwest quadrant, bounded roughly by 17th Street NW to the east, Rock Creek Parkway to the west, Constitution Avenue NW to the south, and Pennsylvania Avenue NW to the north. Much of Foggy Bottom is occupied by the main campus of the George Washington University (GWU). Foggy Bottom is thought to have received its name due to its riverside location, which made it susceptible to concentrations of fog and industrial smoke, an atmospheric quirk. The Foggy Bottom neighborhood not only borders Downtown Washington D.C., but also borders the very affluent neighborhood of Georgetown as well. Residents of Foggy Bottom also have convenient access to Georgetown University as well..
