Arbor Hill Historic District–Ten Broeck Triangle
During the Great Migration of the 1920s, many of the African Americans who came north to Albany from the Southern states settled in Arbor Hill, an area that had been one of the first where their predecessors had settled in the city It came to be regarded as more desirable among newcomers than their other destination, the South End. Residents of that neighborhood often moved to Arbor Hill after they had made some money. African Americans displaced by the construction of what is now the State Department of Education Building in 1912 also resettled in Arbor Hill. As early as 1922 many of the city's prominent African-American institutions and organizations, such as churches and social clubs, were located in Arbor Hill. This growth led to the name being applied to the larger area it presently refers to, extending north to the railroad tracks, west to Northern Boulevard (now Henry Johnson Boulevard) and south to Sheridan Avenue.
Mission Hill, Boston
Like the adjacent neighborhood of Jamaica Plain to the south, Mission Hill was once a neighborhood of adjacent Roxbury before Roxbury's annexation by Boston. According to maps from the period, it was often referenced as Parker Hill (which is the name of the geographic feature in the area). After annexation (and more rapidly in recent years) the area slowly came to be considered a separate neighborhood of its own right. The majority of government, commercial, and institutional entities list "Mission Hill" in the breakdown of Boston neighborhoods and its boundaries generally agreed upon.
