<P> Soon many people followed Kāva to the Alborz mountains, where Fereydun was now living . He was now a young man and agreed to lead the people against Zahhāk . He had a mace made for him with a head like that of an ox, and with his brothers and followers, went forth to fight against Zahhāk . Zahhāk had already left his capital, and it fell to Fereydun with small resistance . Fereydun freed all of Zahhāk's prisoners, including Arnavāz and Shahrnāz . </P> <P> Kondrow, Zahhāk's treasurer, pretended to submit to Fereydun, but when he had a chance he escaped to Zahhāk and told him what had happened . Zahhāk at first dismissed the matter, but when he heard that Fereydun had seated Jamshid's daughters on thrones beside him like his queens, he was incensed and immediately hastened back to his city to attack Fereydun . </P> <P> When he got there, Zahhāk found his capital held strongly against him, and his army was in peril from the defense of the city . Seeing that he could not reduce the city, he sneaked into his own palace as a spy, and attempted to assassinate Arnavāz and Shahrnāz . Fereydun struck Zahhāk down with his ox - headed mace, but did not kill him; on the advice of an angel, he bound Zahhāk and imprisoned him in a cave underneath Mount Damāvand, binding him with a lion's pelt tied to great nails fixed into the walls of the cavern, where he will remain until the end of the world . Thus, after a thousand years' tyranny, ended the reign of Zahhāk . </P> <P> "Zahhak Castle" is the name of an ancient ruin in Hashtroud East Azarbaijan, Iran which according to various experts, was inhabited from the second millennia BC until the Timurid era . First excavated in the 19th century by British archeologists, Iran's Cultural Heritage Organization has been studying the structure in 6 phases . </P>
