Could it be possible to make a city that looks like this

[Lach77]

There's not much in the way of BATs that i've seen that cover curved city walls or Byzantine styled architecture but could it be possible to make something like this?

For curved city walls you could repurpose JENX' quays and for an ancient touch you could use psycholu's many temples. That said, the hardest part is gonna be dealing with slopes. You'd need all the on-slope walls you can get (like these) or better yet, learn to make your own.

While on the subject of content creation, the best way to achieve such a city of course would be to BAT these kind of buildings yourself. Than you could make all kinds of crazy curved stuff with proper overhang and such. Not an easy feat by any means but I imagine it would be possible eventually. It really depends on how much time and effort you're willing to invest.

(So, yes, you can.)

Haha wow so someone has already done it. Good job although it still needs the curved on-slope walls. I reckon that would indeed be the hardest part especially since SimCity4 works on a grid.

And that temples mod looks really good, I haven't seen that before so its nice to have a touch of Classical architecture which is a definite inspiration for Peter Jackson's Minas Tirith. Although a true recreation would indeed need some Byzantine styled BATs.
