Briefly learned from Daily Mail that several secret dungeons were found in Tokat Castle, located in Turkey.
Vlad the Impaler, also known as Wallachian Prince Vlad III was reportedly held as a prisoner in 1442 after a diplomatic meeting. After he was released, it is believed that he was responsible for the murders of 20 000 people, which led to his arrest. While many people believed that Vlad the Impaler was being held in Romania, it has been reported that this discovery of secret dungeons could be where Vlad the Impaler was held a prisoner during the 15th century.
Builders have also reported that tunnels and a military shelter have been found.
Archaeologists find the entire discovery very mysterious.
