Reaching the Incan citadel of Machu Picchu is historically famous for its difficulty. The site’s remote location was a factor in the Spanish conquistadors overlooking it as they swept Peru for its riches. Archaeologist and politician Hiram Bingham had been seeking another “lost” Incan city when he happened across it in 1911.
