Templo Mayor and the Cathedral Metropolitana

I decided to group these two vastly different places together in one story as they essentially occupy the same space, one built sort of on top of the other.

The cathedral is the largest in the Americas, begin in 1525 very shortly after the Spanish conquest of Mexico. It is huge of course, and very baroque. It has really suffered from the sinking soil issue but somehow they have engineered changes underneath to stabilize it. How, I have no idea.

Templo Mayor is a Aztec period temple started around 1325 or so and served as the center of their capital, Tenochtitlan. As was typical then, temples were expanded by essentially just building over the existing one with a new layer. This one ended up with 7 distinct layers and reached a height nearly the same as the present day cathedral. When the Spanish arrived, they essentially destroyed it. (Like they typically did everywhere.) The area even spent time as a city dump. It was not until an unexpected finding in 1978 that the excavations began and unearthed this amazing area. Below you will see a shot of a model of the area showing that the Aztec structures fully covered the entire zocalo area including the site of today’s giant cathedral.

The cathedral Metropolitana, largest on all of the Americas. And with a major sinking issue.
This model helps show how large the Aztec complex was. The cathedral occupies the area in front of the main temple. The other ruins are just there buried below existing buildings.
I took this to show the relationship of the ruins to the present day cathedral complex. If both were standing complete and undamaged, they would be of similar height! Hard to believe that this was just re-discovered less than 50 years ago.
Found at the top level of the main temple.
Pretty cool for just laying there, huh? And they were just there between different layers of the various expansions of the temple. In the past, they surely occupied a more important position.
Cornerstones! Yes, the Aztecs also used cornerstones to date new construction. There are two here. Can you find both? Their dates are about 20 years apart.
