Ollantaytambo is a small town and an archaeological megalithic site in southern Peru, 60 kilometers northwest of the city of Cusco. Located at an altitude of 2,792 meters (9,160 feet) above sea level in the district of Ollantaytambo, province of Urubamba, in the Sacred Valley.
Ollantaytambo, more than 10000 years old
Archaeologists believe, Ollantaytambo is more than 10000 years old, it was built upon the ruins of a much older city.
This most amazing ancient mystery and Power place, raises questions similar to those regarding Pyramids of Giza, Machu Picchu, Pasqua Island and other well known sacred sites on the planet. All of these ancient megalithic sites have common elements that no one can explain today. 
In Ollantaytambo, the stone masonry is composed of blocks weighing sometimes over 50 tons, placed on top of each other with a mind boggling precision. With not even a tiny space between them.
It seems those stones’ origin was from a quarry, on another mountain, at the other side of the Sacred Valley, across the Urubamba river .
This image of the Valley, gives us some proportions.
Even without any stone on your back, crossing the valley and climbing those mountains, does not seem to be easy!
Again the same questions raise:
- How were these stones cut out of the mountain?
- How were these blocks carried to the sacred site?
- What technology did the ancient builders use to build those high precision masonry walls, without using mortar.
- How come some details of the stonework are precisely the same as those we can observe on other ancient sites at the other end of the planet?
- What was the connection between those sites?
Experts claim that even with the most up to date technology equipment that we have today, we could not reproduce what has been done by these ancient times magicians who built Ollantaytambo.
Again, the vision that I have received about those mysteries described here, seems to be, more realistic, to me as an energy seer, than any theory or speculation brought up by experts up to now.
Somehow, I have the feeling, that we soon will receive the answers, from recent studies in the realm of quantum physics.
