Commonwealth Works Site

The Commonwealth Works Site is an historic industrial archaeological site in Norwich, Connecticut. Located near the Yantic Falls on the Yantic River, it was the site of a major industrial facility developed in the mid-19th century, with an industrial history dating back to the 18th century. Charles Augustus Converse had consolidated water rights at the falls, and built a large complex which housed a number of different water-powered enterprises, including the gun factory of Ethan Allen, a gristmill, sawmill, woolen mill, nail factory, and a cork-cutting factory.

The site was listed on the National Register of Historic Places in 1998.
