^ Yes, it's not that noticeable, but I'm used to stare at pixels.
I also finished making a wonder from the centerpiece, which is the Large Circular Sanctuary at Sarmizegetusa Regia.
A bit of history:
After the second Dacian war ended, in 106 AD, the last king of the Dacians, Decebal (Decebalus), committed suicide, rather than suffering the dishonor of being captured by the Romans after he was defeated. Until then, the capital of Dacia has been at the city of Sarmizegetusa, a very well fortified place in the Carpathian Basin.
However, when the Dacians were defeated, most of Dacia was turned into a Roman province, or actually into more than one Roman province as the region was big. Then, the capital of the Roman province "Dacia" was not used any more. Instead, the Romans hired local architects and built a new city, Sarmizegetusa Regia Ulpia Traiana being its full name.
The city became the biggest and richest in Dacia, and it contains a sacred area, with 3 sanctuaries and a lot of buildings. Only ruins remain from it today, but it has been easily located and many reconstructions, accurate enough I'd say, were made. Here are some photos from Sarmizegetusa Regia:

You can see in the General view a big round thing in the bottom right corner. That's the large circular sanctuary.
So here's my wonder, The Large Circular Sanctuary from Sarmizegetusa Regia Ulpia Traiana:
Well, don`t I feel stoopid now.. 
Dacia does deserve it's own city sets, I'm glad you've taken it on.
