The Bigelow brothers, Erastus and Horatio, had established the Bigelow Carpet Company in 1854. A number of mill buildings were constructed along Union Street in Clinton the 1850s. The company grew rapidly and soon constructed another group of woolen mills along Main Street in 1864-1866. After the death of Erastus Bigelow in 1879, the company continued to expand and soon developed the property on Union Street, constructing a new mill building and rebuilding the earlier structures to create an architecturally unified complex. After the mill closed in 1932, these buildings were used as a warehouse and were partially vacant. In the 1970s, the Nylon Products Company (Nypro) rehabilitated the structures for their own manufacturing use.

The building pictured above was built in 1886. The tower to the rear, on the left side of the picture, is part of another building, which is attached to the 1886 building. It was originally constructed in 1855 and was rebuilt in 1885.

The picture above shows the 1855/1885 building’s other tower, which is located where it connects to a third building, built in 1857 and also rebuilt in 1885.

The building in the above picture, the largest in the complex, was constructed in 1907. It is separated from the other buildings by School Street, but is reachable from them by elevated walkways.
