Marco Polo is a serial in the British science fiction television series Doctor Who, which was first broadcast in 7 weekly parts from February 22 to April 4, 1964. Although audio tracks and still photographs of the story exist, none of the footage of this serial has survived. This is the first "pure historical" Doctor Who story, in that there are no science fictional elements other than the fact that the Doctor and his companions have travelled to the past.
The TARDIS lands in Central Asia in 1289, where the First Doctor and his companions fall in with Marco Polo as his caravan makes its way along the fabled Silk Road from the Pamir Plateau, across the treacherous Gobi Desert and over the Himalayas to end up in Peking at the height of its imperial power.
