Considered one of the city’s most haunted buildings, Old Charleston Jail has a gloomy history. When it still operated as a prison, it was notorious for being so overcrowded and disease-ridden that hundreds of inmates lost their lives due to the harsh conditions. As such, many of their restless spirits are said to roam the dark halls. Today, the Old Charleston Jail is a popular destination for ghost tours, with some visitors even reporting strange sounds and cold spots throughout the building.
