Prior to the discovery at Sechin Bajo, archeologists considered the ancient citadel of Caral Peru is one of the oldest in the Western Hemisphere, at about 5,000 years old.
Scientists say Caral, located a few hours drive from Sechin Bajo, was one of six places in the world - along with Mesopotamia, Egypt, China, India and Mesoamerica - where humans started living in cities five thousand years ago.
The dating done by the German archeologists puts it at about 5,500 years, but others can be older depending on what else is found, Perez said.
Earlier finds near Sechin Bajo 3,600 years old.They have a highly developed understanding of architecture and buildings. It can be clearly seen in the fact that the materials they use to survive very long, Peter Fuchs, one archaeologist, told the newspaper El Comercio.
Social meeting place Fuchs and his colleagues found was built with stone and brick.
Hundreds of archaeological site shut down Peru, and many ruins built by the Incan Empire culture that used to be very powerful, which reached its peak in the 16th century, just before Spanish conquerors came in what is now Peru.
