There are historical places in this mod, like Aachen, Cologne, Bonn and so on. Their ingame scenes often don't match, because there are often custom made generic scenes or still native scenes. Making a scene for Orleans for example requires knowledge about the look of Orleans mid 13th century and the scene you make has to reflect the past. You can't just make a scene and call it Orleans.
If there is any native Russian speaker here, just write in Russian what I and others have asked for, namely references for the scenes Mazai made.
Surely you can't expect everything to be historically accurate.
There's always gonna be a mismatch since it's hard to find plans of the towns and castles of the times. Even if they are available, doesn't mean they can be the same. It's a game not a history lesson.
They do their best to reflect the architecture and other aspects of the game of the period this game is based in. Perhaps you could help by pointing out exactly what's wrong with their work and give them some constructive feedback instead of just saying it's not what it looked like 800 years ago. 
Why don't you read what I write instead of making up shit I never wrote? Where did I write that his scenes are "not what [they] looked like 800 years ago". I didn't say that anywhere!
I simply asked for a reference, like others did, but he still hasn't come up with anything of the sort and he might just waste his time in creating scenes of the top of his head. Neither do I know, if his scenes are really complete, meaning an AI mesh is there, the entry points and passages. Given his understanding of the english language or lack thereof, I doubt he understands tutorials in this forum or the little bit of help to be found in edit mode, nor can I explain it to him.
And you are unaware that I made several scenes for this mod, aren't you? "They do their best" in creating scenes and I am one of them. I find it very hard not to insult folk like you, when you try to lecture me with your ignorance.
