What Peruvian city-dwellers of 5,000 years ago can teach people of today

In a study in contrasts, architects who use sophisticated technology to design state-of-the-art buildings are looking to the oldest center of civilization in the Americas for inspiration—Caral-Supe in Peru. The UNESCO World Heritage Site features advanced engineering and design that, if replicated, could help modern people live in harmony with nature and each other.

“The International Union of Architects met at the UNESCO World Heritage Site [November 6-8, 2015] and signed a document called the Caral Letter, which hails the ancient city as an example of sustainable urban planning and living in harmony with nature,” says Phys.org in an article about the conference.
