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
The northward expansion of the city envisioned by the elder van Rensselaer finally came to pass after 1825, when the Erie Canal was opened. Many new arrivals to the city, drawn by the canal and its economic opportunities, needed places to live and work. They looked north, along Broadway and North Pearl. Some found the mansion neighborhood and the blocks to its west to their liking, enough that city directories of the period show a few residents and businessmen listing "Arbor Hill" as their address. During the 1830s, they built some of the first houses in the district after the mansion. A few from this period, such as 10 Ten Broeck Place and 31 Second Street, survive. Similarly, the mixed-use Greek Revival buildings around the intersection of Second and South Swan were built in the early 1840s.
