In all the time i've played this game this is the first time i have seen an enemy AI build the naval architect. Out of sheer dumb luck i took the town they had built it in and out of curiousity saved my campaign and then went back and forth retaking the town to see if i could take the enemies n.a. and use it myself. After at least several dozen tries i could keep every building in the town but never the n.a.

I know you can't take an enemies capital building so what i am wondering is if the same is true for buildings like shipyard and the guilds. Can you take those type of buildings from an enemy or will they automatically be demolished when you take the town they are built in?

I dont remember for sure but if it a building you are nly allowed one of in your empire I dont think they can be captured.
