Marco Polo in Persia

 In three previous papers, we investigated the travels of Marco Polo using Google Earth and Wikimapia. We reconstructed the Polo’s travels from Beijing to Xanadu, from Sheberghan to  Kashgar, and from Kashgar to Xanadu. Here we propose Polo's travel in Persia. The place of a Mulehet Castle, close to Ferdows in the Tunocain county, is given. It is possible that Marco Polo was referring to this castle near Ferdows, when he was reporting about the Old Man of the Mountain, and not to the Alamut Castle.
