High in the Andes Mountains of Peru lies one of the world’s greatest mysteries: Machu Picchu.
Built in the 15th century by the Inca civilization, this remarkable city remained hidden from the outside world for centuries.
But why was it built?
Was it a royal palace?
A sacred temple?
An astronomical observatory?
Or something we still do not understand?
Researchers continue to debate its true purpose.
At GHRI, we believe every mystery deserves careful research and open discussion.
