Willimantic Linen Company, Mill No. 1, Immediately West of South Main Street, North Bank of Willimantic River, Windham, Windham County, CT

Significance: Mill No. 1 was the first large industrial building erected by the Willimantic Linen Company, in a complex which remained the major source of local employment for 130 years. Expansion of facilities c1862-95 by this company, and its successor the American Thread Company, required additional power supply. American Thread Company rebuilt and consolidated two separate water privileges c1900-1903 at Mill No. 1, which is the oldest surviving component at the American Thread complex. The hydroelectric installations made at this time were typical of moderate-sized industrial sites in New England.
