The team treks high into the mountains of Romania to pay a visit to the Citadel Rasnov, a 13th century fortress that was built to provide protection and defense to the neighboring village below. The castle has been the subject of local legends for years, the most notorious of which tells the tale of two captured soldiers who died in a well on the castle grounds in which they had spent years living as captives.

GHI visits a German fortress whose chambers are haunted by the spirit of a beheaded 13th Century nobleman. Then it's all off to Slovakia, where the team separates legends from facts in the dark halls of Orava Castle.

Macabre rumors of witchcraft, wandering spirits and grave-robbing give GHI and special guest investigator Josh Gates of "Destination Truth" plenty to dig into at the real Frankenstein's Castle in Germany.
