Sheridan Hollow, Albany, New York
On a map made by De Witt in 1790 the name of Arbor Hill makes its first appearance on a map of Albany. In this map Arbor Hill is located in Sheridan Hollow between Orange Street and Clinton Avenue (south and north) and from Chapel Street halfway to Hawk Street (east to west); later Arbor Hill would be the name given to the Ten Broeck Mansion and surrounding neighborhood on the other side of Clinton Avenue, the former village of Colonie. On this same map a "Negro burial ground" is shown along the southern rim of the Hollow, this burial ground does not show up on any subsequent maps and it may never have been plotted and used.
Arbor Hill Historic District–Ten Broeck Triangle
Its fortunes began to slip as the city expanded westward, to new neighborhoods like Washington Park which attracted the city's affluent. As the 20th century began, it gradually became a more middle-class neighborhood, then, after the Great Migration, predominantly African American. As an effective racial ghetto, the neighborhood and its historic buildings suffered the effects of disinvestment and decline. The designation of the historic district, and other efforts by preservationists later in the century, have helped reverse that trend, though not completely.
