Investigate the history and natural history of this underground copper mine and ruins of the oldest surviving state prison in America. Chartered in 1705, the copper mine was the first in the North American colonies and operated for nearly 70 years. The colony of Connecticut purchased the mine in 1773 to create a workhouse and prison for convicted criminals that operated for over 50 years. The site later became a privately owned tourist attraction with a popular dance hall, a World War I tank and even a zoo. Today, the dank mine tunnels, menacing perimeter walls and hulking prison ruins still convey an environment of confinement and awe.
The museum’s 45-acre hillside site with breathtaking views includes the two-acre prison yard enclosed by a 12 foot-tall masonry perimeter wall. Inside the wall is the entrance to the underground copper mine and the prison yard, with its renovated two-story Guardhouse and the standing ruins of four other prison buildings. Named after the famous prison in London, Connecticut’s New-Gate Prison held more than 800 prisoners over the years, including four women and Tory prisoners sent by George Washington during the American Revolution. Located across the street from the prison, Viets Tavern (currently closed) is the unrestored, mid-1700s home of first prison warden Capt. John Viets and his wife Lois.
The State of Connecticut re-acquired the site in 1968, opening it to the public as a history museum. It is now a National Historic Landmark and State Archaeological Preserve.
