Today was my day for walking through history. I decided to cheat it and join a tour to go to Teotihuacan, as I didn't want to miss out on any of the stories behind the places. I'm glad I did too, as there is a long history when it comes to the Mexicans. The day started out in the Zocola, where I learned that Mexico City is actually set upon a foundation of water...hence it is sinking. So those quirky buildings that lean are actually gradually collapsing. Essentially, Mexico City is the Central American Venice. The architectural stability of number of their major historical buildings are under threat. The Church of Our Lady of Guadalupe is probably the most affected. Walking through the atrium you feel as though you have entered one of those optical illusion boxes at the science fairs. Just walking around the streets of Mexico you can feel the footpath rise and fall below your feet. For someone as uncoordinated as me, this proves a challenge. However, I am happy to report that I haven't rolled my ankle yet. Then there was the real purpose of my joining a tour, Teotihucan. This mesoamerican city was the largest city in the pre-Columbian Americas. The Pyramid of the Sun is the largest building in Teotihuacan, believed to have been constructed about 200 CE and I climbed to the top of it. This site is one of three sites in the world that reflect Irians Belt constellation, the other two are found in Xian, China and Cairo, Egypt. By visiting this site I have been able to tick off one of my bucket list items. Tomorrow, we go on the hunt for Frida Kahlo!
