Dannemora, located in the frigid Adirondack mountains, its nickname is “little Siberia.” Officially called the Clinton Correctional facility–this foreboding prison is commonly known as Dannemora–named after the town where it is built. The prison opens on June 3, 1845, as a source of free labor for the local mines. Here are three of the most incredible tales from inside its icy walls. First, a desperate convict Kenneth Kimes takes a Court TV producer hostage. Then, a superstar prisoner, Tupac Shakur, stirs up trouble, and finally- two murderers, Richard Matt and David Sweat, attempt a daring escape.
