Old New-Gate Prison & Copper Mine - Seasonal — Attraction in East Granby

Highly recommend to visit it!! Very interesting history, great tour underground (take a jacket, as the temperature is very low there), great insight on the jail history in America.

Great job by guides and everyone who created the museum and works there! Nice gift shop.

Beautiful area around it. There is a very nice picnic area with many tables right outside the walls.

The only thing is when we came out to the parking lot after the tour (which took in total about 2 hours), we found our car's fuel door open and the fuel tank cap hanging down. Someone opened it and tried to steal gas, but either their hose didnt work or they got scared off by someone. I found small marks and scratches on the fuel door from opening it. The gas was still there. Sad. But the museum is located in the middle of nowhere, and with today's gas prices people are desperate. Just be careful. It still shouldn't stop you from visiting this place. The museum...

Have been there several times over many years. It was closed for years for "renovations" but I honestly didn't see any. Staff is wonderful, tour guide is well informed and answered all questions. Above ground accessibility is excellent and well maintained. Below ground I saw no "improvements". It's still very poorly lit, all the old rusted handrails are still there. The "solitary confinement cell" was flooded. Wear a hat/light jacket as water will be dripping on you from start to finish. I wish they would install some pressure treated wood steps/decks along the route. Keep watch for low ceilings and slippery floors! I must say again-the staff are excellent and very accommodating!! PS bring bug spray for when outdoors/above ground and best to go on...

A little grim but highly absorbing, this National Historic Site in East Granby started out in the early-18th century as a copper mine, in operation until the 1740s.

After that the tunnel network was converted into Connecticut’s first official prison, also used for British prisoners of war and Loyalists during the Revolutionary War.

You can access around half of the extant tunnels on a tour, exploring a place that was referred to as “Hell” by its inmates.

On the surface are the ruins of structures from the turn of the 19th century, including five brick and masonry buildings and the prison wall.

The Old New-Gate Prison & Copper Mine reopened after almost a decade of renovations in 2018, and you can come to look around from...
