The Kukulkan Pyramid at Chichen Itza was a terraced monument as opposed to being a true pyramid form such as we see in Egypt. There were clear reasons for this departure from Egyptian architectural practice because in the West, pyramids convey specific numbers which can enable us to see why they were built where they were upon the earth. This is how you decode the longitude of this structure. (Based on the Great Pyramid at Giza, Egypt being at longitude zero.) 9 terraces x 365 steps x 4 sides x 4 stairways = 52,560 The structure's longitude (based on Giza) is 119 degrees west, 42 minutes and 10.51620648 seconds. Those numbers multiply out to 52559.99998704 A coincidence? Or did they somehow know exactly where this structure was located in relation to Giza. One of the world's most puzzling mysteries I suppose! (Well, it is an imagined coincidence I suppose...lol..)  This structure was built by the Toltecs around 1200ad. The Mayans were driven out after building structures here for about 600 years. Today, the Mayans are the main group of people living in this area.
