 In Zoroastrian eschatology, when the final renovation of the world is near, maidens will enter the lake and then give birth to the "saoshyans", the saviours of humankind.The fire temple is on a terrace behind high walls and is protected by two forts, whose remains are respectively known as Kok-e Zal and Chehel Dokhtaran.Collectively, the ruins are called Qal'a-e Kafaran "Fort of Infidels" or Qal'a-e Sam "Fort of Sam," the grandfather of the mythical Rostam (one of the fortresses here is named "Rostams castle").
