Moray, Peru.

Moray is a collection of four natural sinkhole formations that were shaped and embellished to create a landscape architecture masterpiece on the north side of the Urubamba River in the Sacred Valley.  A commonly held hypothesis was that Moray was built as an agricultural experimental and control center, which became the common wisdom on the site’s purpose and function.  WPI commenced field studies at Moray in 2005 using this agricultural research station hypothesis, but found that what we saw and measured did not fit the theory.  Additional field trips were conducted through 2010 to collect more data and to verify existing data. 

The evidence demonstrated that the agricultural research station hypothesis could not be proven and that Moray was built by the Inca as a place for religious ceremonies.  WPI wrote a book on Moray titled, Moray: Inca Engineering Mystery, available from ASCE Press and Amazon.com.
