Mills on the State & National Register

Mills throughout the state of Connecticut have been recognized for developments in technology and production, and for the varied architectural forms that accommodated manufacturing processes. As of 2017, nearly 240 factories and 8 industrial archaeological sites have been listed on the National Register (and thus the State Register). Another 41 mills and 8 archaeological preserves are on the State Register for their role in the industrial development of Connecticut.

The Making Places initiative of the Connecticut Trust for Historic Preservation has documented more than 1,200 mills, factory complexes and machine shops not previously recognized with a historic designation. Of those, more than 400 have been identified as candidates for State Register listing; many more resources may be worthy of future consideration.

Listing on the State and National Registers is an honorific designation. However it makes properties eligible for important preservation incentives such as the state and federal Historic Rehabilitation Tax Credits, often essential in an economically complex and challenging redevelopment puzzle.
