Libby Prison was a Confederate prison located in Richmond, Virginia, during the American Civil War. It was originally a tobacco warehouse before being converted to hold Union soldiers. The prison became notorious for its overcrowded and unsanitary conditions, leading to high mortality rates among inmates. The prison housed thousands of Union prisoners from 1862 until its closure in 1865. Many prisoners suffered from malnutrition and disease due to inadequate food and medical care. After the war, Libby Prison was dismantled, and its remnants were used to create a museum in Chicago, Illinois, to commemorate the experiences of those who were imprisoned there.
