Old Newgate Prison

The stone structure features underground tunnels, guard towers, and thick walls constructed from locally sourced materials during the American colonial period.

The facility operated from 1773 to 1827 as a state prison, initially utilizing abandoned copper mine tunnels to house criminals in subterranean cells.

The prison complex demonstrates early American penal practices through preserved cell blocks, work areas, and administrative buildings from the eighteenth century.

The site offers guided tours from May through October, with special evening programs and educational workshops about colonial justice systems.

Before becoming a prison, the facility operated as Connecticut's first copper mine, with tunnels extending 67 feet below ground level.
