Meridian Hill is a small urban neighborhood in Washington, D.C., located in Northwest D.C. Meridian Hill is often considered to be a part of the larger neighborhoods of Adams Morgan and Columbia Heights, which it sits between. The neighborhood is primarily residential, though it also hosts a notable amount of diplomatic missions and embassies. Meridian Hill was developed as part of the City Beautiful movement in the late 19th century, when socialite Mary Foote Henderson embarked on a major initiative to turn Meridian Hill into the city's most prestigious area. While the neighborhood lured many prominent figures to build mansions and embassies, Henderson did not achieve her goal of building a new Presidential Mansion on the central area of the hill, which was eventually developed into Meridian Hill Park.
