History

North Grosvenordale was the site of early small textile mills, probably erected in the early years of the 19th century. The mill located here remained relatively small until after the American Civil War, when it and the associated water privileges were purchased by William Grosvenor, an investor from Providence, Rhode Island. Grosvenor also purchased a second mill further south, where he built a large new mill in 1868, calling that village Grosvenordale. When he built the large brick mill standing here in 1872, he renamed this village North Grosvenordale. This mill produced fine cotton fabrics, and was one of the longest-lived and most successful textile businesses in northeastern Connecticut.
