Old New Gate Prison & Copper Mine
East Granby, Connecticut
Description

The underground tunnels of an abandoned copper mine began to be used as a prison in Dec 1773. Over 800 inmates were confined here until the facility was closed in 1827.

The presence of copper ore on the site was noted in 1705 and it became one of the first commercial mines in the British Colonies. It was not a money-making venture, however, and work was abandoned in the 1750's.

Visitors enter the prison yard through 12' tall walls. The brick guardhouse still stands and houses exhibits, but only ruins remain of the other prison buildings. A modern stairway provides access underground where air temperature is always in the 50's. The visitor center contains a gift shop.
