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.
Arbor Hill Historic District–Ten Broeck Triangle
By 1870, much of the district had been developed. The lavish houses in particular that lined Ten Broeck Street gave it the popular name of "Millionaire's Row." Many had been built by lumber merchants and overlooked the Lumber District, the yards down by the canal and river where they did their business. Another church, Sweet Pilgrim Baptist, was constructed in 1876 at the Clinton Avenue intersection, giving the district a distinctive southern gateway. At the north corner, the polygonal home at 105 Ten Broeck featured an iron mansard roof, a hallmark of the contemporary Second Empire style. Some of the existing houses, such as 8 Hall Place, also had mansard roofs added when they were expanded with third stories.
