Machu Pichu is a 15th-century Inca site located in the Andes Mountains in Southeast Peru. Click an image to enlarge.
Bonus picture: wild llama roam freely around the site, which led to this epic photo-bomb that I just had to share.
Most archaeologists believe Machu Pichu was built as an estate for the Inca emperor Pachacuti who ruled from 1438-1472.
It was built around 1450 but abandoned a century later when the Spanish invaded the region.
The combination of the Spanish invaders, as well as a number of epidemics of European diseases including influenze, typhus, diptheria, measles and multiple outbreak of smallpox led to the fall of the Inca Empire in the late 16th-century.
