To me, the most amazing thing about Tartarian architecture, from an esthetic perspective, is that no two of their structures are the same, yet all are of a kind across the entire globe.

I'm convinced they are not the work of a single architect. Rather, I think the Tartarians had an elevated sense of beauty beyond any we see today. No such buildings can be built today from a technical standpoint, but it may be even more significant that they cannot be built from an artistic standpoint. As in the above example, no one sat down with a clean sheet of paper.
