Archaeologists have discovered what they believe is the dungeon that held Vlad the Impaler — the inspiration for Bram Stoker's character Dracula.

The team found dungeons, tunnels, and a military shelter in Turkey's Tokat Castle, where Vlad the Impaler was reportedly held in the beginning of the 15th century. The archaeologists discovered two dungeons during the castle's restoration work, which began in 2009. The restoration work led to the discovery of secrets tunnel between the castle, a military shelter, and the Pervane Baths.

The archaeologists believe Vlad the Impaler — a.k.a. Wallachian Prince Vlad III — was held in the dungeons by the Ottoman Turks in 1442. Tokate was conquered by the Seljuk Turks in the 12th century, and it became a part of the Ottoman empire in 1392. Tokat Castle, a ruined citadel, is in the hills above the city.

"The castle is completely surrounded by secret tunnels. It is very mysterious," archaeologist Ibrahim Cetin said in a statement. "It is hard to estimate in which room Dracula was kept, but he was around here." Meghan DeMaria
