Today in 1773, Newgate Prison, the first penal institution to open in Connecticut, received its very first prisoner: 20-year-old John Hinson, who had been convicted of burglary and sentenced to ten years of imprisonment. Newgate Prison was built on the site of a former copper mine in East Granby which had opened in 1705 as one of Connecticut’s first large-scale industrial ventures and the first chartered copper mine in the American colonies. One the mine went bust in the mid-18th century, colonial authorities figured the various tunnels bored deep into the hillside would be ideal for housing prisoners convicted of serious crimes like burglary, adultery, and murder.

Captain John Viets, whose family homestead was located across the road from the former copper mine, was the first overseer of the new prison. He and the colonial authorities who had constructed the prison were confident that the design of the converted mining tunnels – which were located below vertical shafts that were 25 and 60 feet deep — would render it impossible for inmates to escape.

Viets was quickly proven wrong, however, as John Hinson managed to escape only eighteen days after he was admitted to Newgate Prison. In a letter to the General Assembly defending themselves, the prison’s three guards swore that Hinson must have had an accomplice lower him a rope down one of the mineshafts, since escape would be impossible otherwise. Viets was forced to place an ad in the Connecticut Courant offering $10 to anyone who could assist in the apprehension of the fugitive Hinson – an offer that ultimately went unclaimed.

Hinson’s escape led to a number of changes at the newly-opened prison, including the hiring of more guards and larger, more extensive fences around the property, including a 12-foot-high stone wall that can still be seen on the property today. Hinson was not the only prisoner to make a bold and successful escape from Newgate Prison; within a few decades, the institution had developed a dubious reputation for terrible security as prisoner escapes – and subsequent ads offering rewards for their return – became common. During the fifty years Newgate operated as a prison, nearly ten percent of its inmates managed to escape. Some inmates, like serial offender Richard Steel, managed to escape several times. During the American Revolution, several Loyalists were held at Newgate Prison, a move denounced as unnecessarily cruel by supporters of the King. Increased concern about security issues and the rising costs of maintaining the old prison site motivated state officials to close prison operations at Newgate in 1827, transferring all of its prisoners to the newly-built State Prison in Wethersfield.

Today, the Newgate Prison and Copper Mines site is once again seasonally open to the public as a historic museum, after an extensive, nine-year restoration to help stabilize the old stone ruins above ground and old mining shafts below ground. The site is managed by the Connecticut State Department of Economic and Cultural Development.
