S02E01 Wicklow's Gaol

The team travels to Ireland to explore Wicklow Gaol, a prison built in 1702 that held around 780 inmates during the Great Famine. Now functioning as a museum, it has gained notoriety for eerie occurrences, including claims of people being shoved or touched by invisible entities, sightings of bloodstains on the ground, and the appearance of mysterious shadows and fog.
