Down in the Earth-bastion of the castle in the Waxworks you can personally meet the characters of Stars of Eger novel (the title of the English version is: The Eclipse of the Crescent Moon).
In the cellars the famous characters of the novel are waiting for you; it is like a little Madame Tussaud's where the stars are the characters of the novel. Meet István Dobó personally, then stand face to face with a Turkish soldier. Having finished being a guest at Suleiman sultan, descend even deeper, into the secret tunnel. This short section is from the oldest period of the castle and so much unspoilt, that the floor of the corridor is not even covered, so you are walking on the hill itself on which the bastion was built!
