Old New-Gate Prison & Copper Mine is nationally recognized as the first chartered copper mine and first state prison in early America. As a museum we strives to engage with historic and contemporary issues through the exploration and discovery of the site as a copper mine, prison, and tourist attraction. 

Old New-Gate also houses the first ever Re-entry Hall of Change – a place to honor formerly incarcerated men and women who have made a great positive impact in their communities.

Whether you are looking to discover a piece of Connecticut’s rich history, or to think deeply about the nature of crime and punishment; to explore 75 feet below the surface through the dark and winding paths of the old copper mine, or simply to make memories with loved ones, your authentic experience at Old New-Gate awaits.
