VIDEO: Hiram Bingham in Machu Picchu, 1949

Hiram Bingham returned to Machu Picchu in 1949 for the Chrysler-sponsored Travelogue documentary series.

A few decades after the 1911 rediscovery of Machu Picchu, the Travelogue series visited the Inca citadel with the National Geographic explorer-turned U.S. senator Hiram Bingham.

"A railroad and highway have improved the situation for tourists," narrates the Belgian traveler Armand Denis, "but even today the last few miles are on foot or horseback over a steep climb."
