Someone did look into exactly that. There is no supporting document regarding the actual height. And it does look like it is exaggerated for impact purposes. So they did have towers, they were clearly higher than the rest of the other buildings... Might have been this tall? Maybe. Or maybe not.

What are you referring to? Who looked into it? Are you citing something?

I think they might be referring to this video? https://youtu.be/ikg3-GQLg3g They traveled to the city and spoke to an actual historian on the matter. The "more accurate" model appears in the last 20s of the video if you are just curious about what our best guess of the actual appearance of the city is.
