Walk the copper-mine tunnels and prison ruins.
East Granby · Hartford County · Connecticut
Eighteen square miles. One American treasure.
The smallest town in the set guards one of the strangest and greatest historic sites in America — and wraps quiet hill roads around it.
Why East Granby
What living here actually feels like.
Old New-Gate Prison & Copper Mine in East Granby was America’s first chartered copper mine and, later, a Revolutionary-era prison whose ruins you can walk today. It is a state park, an archaeological site and a story no other town can tell.
Around the landmark, East Granby is ridge-and-valley residential — modest, rural, practical. Route 20 puts Bradley International Airport effectively next door, and Sage Park’s business campus keeps taxes sane without turning the town inside out.
