Culture defense + walls are not stackable?

[jmb777]

I'm playing my first warlord-level game (I'm the Mongols) and the French have walls around some cities. One such city shows a +50% defensive bonus. When I go to attack, the game lists a +50% defensive bonus for the city. My question is ... don't walls (+50%) and culture (the city should probably be at +40%) bonuses stack? I'm confused.

I don't know this by experience because I've never built walls.

Nope, the higher value is used for the defensive value. Walls (and castles) reduce the bombard damage from siege though. Citadels even more so.

Thanks a lot.

Chichen Itza does stack (+25% in all cities). It's not worth building though.
