>>105602444>they built a pyramid on top of another buildingNot sure which structure they're you're talking about, you could argue dozens of structures there are an example of that, which actually segues nicely into...
>but the question is: how the fuck did they build these things?Honestly, generally, Mesoamerican architecture is not that complicated. Stone architecture was generally a fill of rough or roughly processed stone with limestone mortar, and then that was covered with more precise brickwork, which was then covered in smooth limestone stucco/plaster, and then on top of that you had painted murals, sculptural accents, engraved reliefs, etc. Pic shows the fill, bricks, and stucco being applied sequentially. When you see ruins today in Mexico, Guatemala, etc, you're generally seeing the inner fill or bricks.
What also made it less complicated is that structures were often built incrementally: Small temples/pyramids would get encased like russian dolls with new, bigger construction phases over time as new kings took power or nobles wanted to sponsor a project. You can see this in
>>105601223. So many structures were built up over many centuries or over a millennia.
Alternatively, rather then just enlarging the structure like a Russian doll, you sometimes had temples or palaces "branch out" like a fractal, with wider platforms, secondary temple spires sprouting up, or new rooms/halls being added, and over time those could continue to branch out and expand into big connected acropoli complexes.
You can't see it from the view in
>>105601223, but that is ALSO a larger acropolis connected to other temples in addition to being a Russian doll type expansion (see https://i.imgur.com/CWBsiKw.jpeg for a view of the acropolis and other nearby structures), and in
>>105600268 you can see many examples of that, most obviously the Central Acropolis next to the Palace Reservoir (open the image fullsize and look at the maps, then compare those to the model).
