Culture Penalty?

[Legionem Insanis]

Is there any kind of culture penalty in M2TW? I dont see any indicator in the settlement stats.
I notice the buildings display their culture type (ie.:northern european, eastern european, etc) if they are presumably from a different culture.
Does this affect settlement happiness? Seems the ones with more of these windows are more unhappy but I could have enemy spies there.

Yes, the more buildings in your settlement you have that are not your building type, the happiness will go down. If there is a Townhall that is not under your building type, just demolish it and build your own, Always!

Religion is the thing that effects the happiness the most for foreign settlements, always Exterminate other religions cities and build a Church and Townhall right away.
