Downtown Cohoes Historic District

The Downtown Cohoes Historic District takes up 35 acres 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.
