Downtown Cohoes Historic District  The Downtown Cohoes Historic District takes up of the city of Cohoes, New York, United States. Many of the 165 contributing properties date from the 1820-1930 period when the Erie Canal and Harmony Mills were the mainstay of the city's economy. It was recognized as a historic district and added to the National Register of Historic Places in 1984. After years of neglect and decline, it has recently started to see an upswing in business activity due to its historic character and the city's efforts to protect it. It is a roughly triangular area encompassing most of the city's business district, along the axes of Ontario and Remsen streets. Most of its buildings are contributing properties, with only a few late 20th-century intrusions; most of those are residential or commercial and in-use but they also include several churches, factories, a train station and the city hall. They range in architectural styles from Federal to Art Moderne. One building within the district, Cohoes Music Hall, was listed on the National Register before the creation of the district. Another National Register listing, the Silliman Memorial Presbyterian Church, was demolished in 1998. A similar fate befell a church building designed by Richard Upjohn after it burned in 1894, but its rectory survives. The district is bounded by Oneida Street on the north and the former Delaware and Hudson Railroad (now CP Rail) tracks on the east. On the west it takes the form of an irregular diagonal beginning at the intersection of Columbia and Remsen streets at the southeast, cutting through the middle of several blocks, and ending at Ontario and Olmstead streets in the northeast. Directly adjacent to this northeastern corner is the separately-designated Olmstead Street Historic District, which includes the Ogden Mill and row houses built for textile workers, a short distance to the northeast. To the north and east flow the Mohawk and Hudson rivers, respectively. Most of the land in the district is developed in the form of commercial and industrial buildings, with a few churches and Cohoes's city hall. There are some vacant lots on the edges, most notably the former canal bed at the northeast corner. The land is relatively level, reflecting the nearby river confluence. The main route through the district is NY 470, which follows Ontario Street. It leads east to Troy across the river via the 112th Street Bridge and west to Colonie. The north-south routes 32 and 787 are located along the Hudson, just to the immediate east of the district.
