Special Building bonus even if controlled by vassals?

[Nordic]

Is the bonus you get from special buildings, on your whole Empire, always active if the vassals fulfill conditions for these buildings?
Or do you need to own this county/duty yourself?

I ask because a lot of the benefit/values from these special buildings are hard to compare if active or not.

Seems like you only get them if they're part of your Domain. Example, my vassal holds Stonehenge and while he gets the +2 realm learning bonus, I do not. So eventually I'm going to have to go on a revoking spree.

Also seems like the same applies to military buildings that boost your men-at-arms. So building a Military Camps in your Vassals' territory will only improve *their* archers, not yours as far as I can tell.

Thx for your answer.
I gues this also happens to "normal" buildings giving you bonus on troop-stats or greater number of knights?

Seems so. The ones that give you more knights and stuff all the way over in the extra right-hand slot are actually special Duchy buildings that you can only build in Duchy capitols you control, too.
