The Downtown Cohoes Historic District takes up 35 acres (14 ha) 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.

Lock 18 of the Enlarged Erie Canal is located off North Mohawk Street in Cohoes, New York, United States. It is made of stone blocks 3 by 2 by 1.5 feet (90 by 50 by 40 cm) in size, roughly 150 feet (46 m) in length, laid in a random ashlar pattern. The lock's wooden gates are no longer extant. The lock was built as part of an 1837-1842 plan to make the canal bed larger, heading off competition from railroads, and allowing a detour around the section of canal between Albany and Schenectady to the south, which had fewer locks and was difficult to navigate. Holmes Hutchinson, a canal engineer who later became chief of that department and a director of several railroads, surveyed the route and drew up the plans for all locks in the mid-1830s. The canal was relocated slightly within the city of Cohoes; North Mohawk Street today parallels the original alignment, with sections of the original canal kept open to provide water power to nearby mill complexes along the Mohawk River.Ten of the locks from the Enlarged Erie Canal remain within Cohoes. Lock 18 was individually listed on the National Register of Historic Places, added in 1970 in recognition of the high quality of its remaining stonework; the remainder of the locks on city-owned land were added to the National Register in 2004 as a non-contiguous historic district. A city-owned trail along the former towpath allows visitors to see them. There is also a small parking lot along the street northeast of the lock with an interpretive sign.

Cohoes Falls [Kahon:ios, Mohawk for "High Falls"] is a waterfall on the Mohawk River shared by the city of Cohoes and the town of Waterford, New York. Discovered by the indigenous people, the falls are called Ga-ha-oose or Ga-ho'n'-yoos by the Mohawks, which means "High Falls." Cohoes historian Arthur Masten wrote in his 1880 history that the phrase might mean "Potholes in the River," referring to the potholes that appear in the riverbed when it is dry. However, Kanatsiohareke (Kanatsiohare) and Canajoharie, NY bear names with reference to this meaning in Kanien'ké:ha. In the oral and written tradition of the Haudenosaunee (Iroquois), the Cohoes Falls are the site where The Great Peacemaker, performed a feat of supernatural strength, convincing the Mohawk people to become the founders of the Iroquois League of Nations or Confederacy. Some historians believe the Mohawks launched the Confederacy as early as 1142 CE, though other experts report dates ranging from 1450–1650. Celebrated by 18th-century travelers in letters and journals, the Cohoes Falls, also called The Great Falls of the Mohawk, were regarded as the second-most beautiful cataract in New York State after Niagara. In 1804, the national poet of Ireland, Thomas Moore, visited Cohoes and wrote a paean to the waterfall's beauty: "Lines Written at the Cohos, or Falls of the Mohawk River." In 1831, town leaders built a dam across the Mohawk River to harness the power of the falls to fuel the turbines of the city's burgeoning textile industry. Over the next several decades, the predominant company, Harmony Mills, became the largest manufacturer of cotton in the United States, thanks to its control of local water rights. When all the mills closed in the wake of the Great Depression, city leaders leased the flow rights to a series of power companies, including Niagara Mohawk and Orion Power. The Erie Canal was planned to overcome the navigational barrier of the Cohoes Falls. The original "Clinton's Ditch", the Erie Canal of 1825, was built through the city of Cohoes. The later Enlarged Canal was realigned, yet still went through the City of Cohoes. The Barge Canal, which opened in 1918, bypasses Cohoes and runs through the Village of Waterford via the Waterford Flight of Locks. The Cohoes Falls is 90 feet (28 m) high and 1,000 feet (305 m) wide. Its flow is greatest in springtime, sometimes running at 90,000 cubic feet (2,500 m3) of water per second. The flow varies with seasonal variation of Mohawk River flow as well as with diversions for the Barge Canal locks, power generation, and the Cohoes water supply. During the summer, the falls are virtually dry, revealing shale rock formations that have their own distinctive beauty. The 87-year average flow of the Mohawk River at Cohoes is 34,638 cubic feet per second, but this includes water diverted to the power plant and Erie Canal locks.

Cohoes ( kə-HOHZ) is an incorporated city located in the northeast corner of Albany County in the U.S. state of New York. It is called the "Spindle City" because of the importance of textile manufacturing to its growth in the 19th century. The city's factories processed cotton from the Deep South. As of the 2010 census, the city population was 16,168. The name Cohoes is believed to be derived from a Mohawk term, Ga-ha-oose, referring to the Cohoes Falls and meaning "Place of the Falling Canoe," an interpretation noted by Horatio Gates Spafford in his 1823 publication "A Gazetteer of the State of New York". Later historians posited that the name is derived from the Algonquian Cohoes, a place name based on a word meaning 'pine tree'.
