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
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.
