The Marcahuasi Stone Forest of Peru

Marcahuasi is a plateau in the central Andes of Peru (see Where is Marcahuasi?) on which are found dozens of what appear to be sculptures in stone depicting a variety of anthropomorphic and zoomorphic figures.


Marcahuasi Discovery

Discovered by Daniel Ruzo in 1953, the stone monuments look like knights, warriors, helmets, faces, llamas and more. Despite past research, these megaliths are still shrouded in mystery and in need of more ongoing study to discover their true meaning.


About Me: Luis Ruzo

I am the son of Daniel Ruzo. Since the 1970s, I have visited Marcahuasi whenever I traveled to Peru to see my family and friends. Because I was committed to my academic and later business interests, I was not able to seriously study Marcahuasi until 2010. During that year, I created ECYART, a foundation dedicated mainly to educational purposes, but also instrumental in supporting research. Several years later this website was created as a forum to disseminate the information obtained during several expeditions to Marcahuasi.


Marcahuasi Research Data

The study of the Marcahuasi ruins by the Association for the Study of Traditional Arts and Sciences (ECYART based in Lima, Peru) has been ongoing since 2010.

The goal of ECYART is to develop data that may support the hypothesis that many of thestructures in the Marcahuasi stone forest of Peru are the creation of an ancient Andean culture.

The data obtained in our recent expeditions suggests that the Marcahuasi megaliths of Peru display specific lines of sight.


Ongoing Marcahuasi Research

These lines of sight are also part of our ongoing research and they may be aligned toward important points on the horizon. Most interestingly, the alignments of certain Marcahuasi stone monuments and markers appear to reflect the geometric disposition of the stars in the Pleiades constellation.
