The Lost City in The Clouds, Machu Picchu

Machu Picchu high up in the Peruvian Andes was built by the Inca in the 15th Century. Within 100 years, the Incas conquered a territory that stretched for 3,000 miles from southern Colombia to northern Chile and Argentina. Based on a system of benevolent despotism (no one went hungry or cold), the Incas built a complex, unified regime that imposed sun worship and the Quechua language on dozens of tribes who had been warring among one other for centuries. The domination was such that more than 8 million highland Indians speak Quechua today in seven South American countries.
