Pyramids.

After doing a bit of research regarding pyramids which relate to the Orion constellation I found three major megaliths. These three sites around the world all have 3 large pyramids which are positioned in a way that represents the three stars which make up Orions belt.

The three sites are Giza in Egypt, Teotihuacan in Mexico and Xian in China, We have lots of information about Egypt and their pyramids, a small amount of Teotihuacan's and little to nothing of Xian's. Xian is very mysterious due to China not allow people to excavate or even trespass on the land as it's seen as a spiritual place.

These are aerial views of the megaliths;

Egypt's pyramids can also be seen to stretch even further to represent the Orion constellation.
