Province buildings are of course maintained in the game - you will find a lot of information on geography, population and history of each in-game region there plus the cool graphics thank to Tsar's heroic work. BTW the province buildings are always listed as the first one on the settlement scroll, you can see their icons in Alifertes's AAR quite well - it is the icon that looks like an oval "window" into the province and you will notice that the tiny piece of landscape through it is different for each province (as it should be).
