At the base of the southern slope of the Cerro Zirahuato mountain in the Toluca Valley, in state of Michoacan, Mexico, there is an ancient pre-Columbian ceremonial center containing two magnificent pyramids side-by-side. Only two of the pyramids have been uncovered and studied so far, but other structures also exist nearby.1
The larger pyramid is 38 feet in height (11 1/2 meters tall),2 and is partially collapsed. It features a monumental two-tiered staircase on its western side.
A fuller view of these two main pyramids can be seen in the video below:
From a check of alignments of this site on SunCalc.net, the stairway of the main pyramid appears to be aligned to the winter solstice sunrise, such that you would see the sun rise from behind the pyramid. Note: this alignment remains to be verified on the ground.
Interestingly, the site contains a myriad of petroglyph stones embedded into the pyramids themselves, as well as in the surroundings of the site depicting many symbols of the ancient Religion of the Sun, such as spirals, labyrinths, concentric ring suns, tortoises, etc.
Some of these petroglyph stones can be seen in the video below:
