Actually it's a mixture of Medieval fantasy and Roman times. The original map was far too fantasy-ish for my taste, so I changed as much as I could, but I couldn't just remove landmarks, e.g. the fortress. The setting is not 100% historically acurate, so the map is stuck between the two extremes. Can't help that But thanks for mentioning it so I could point that out.

@Mateus: Thanks I watched the Yale lectures on Roman architecture a while ago (they can be found somewhere in the resource section of the forum). They really helped a lot!
