Machu Picchu 101

|     3:18    |     101 VIDEOS    | Everybody knows that Machu Picchu is an archaeological gem, but I never knew just how precious it was until I wrote the script for this 101 video. I was particularly floored by theinnovations the Inca developed to construct Machu Picchu and have it last for hundreds of years—all without the use of the wheel and other implements found in Europe, Africa, and Asia at the time. This site is a great example of human ingenuity. —Angeli Gabriel, writer/host
