Harlem and Central Harlem is located west of Fifth Avenue and the East River and stretches from 110th Street, or Central Park North, to 155th Street.
Harlem has long been defined by boom-and-bust cycles and dramatic population shifts. In the 1920s and 1930s, the neighborhood was the center of the first Harlem Renaissance, a cultural high point in the history of the American black community. In the late part of the 20th century, Harlem experienced a massive building boom. Newer buildings range in size and style from studios to lofts and luxury condos.
