To destroy or not to destroy (unique buildings)

[Fierro]

How can I find out which unique buildings work with which factions?
In my current Saka campaign when short on cash I've been destroying a few of those unique buildings that give 2000 or 5000 mnai a pop and only provide a negligible 5% happiness bonus.

If the description says the bonuses only apply to certain cultures (like Greek, Nomad, Roman etc.) then they are more or less useless to you and destroying it would not affect you in any way. Other buildings simply give bonuses to all factions, and that you can verify if there is no reference to any culture at all.

But of course if you are a true EB fan, you wouldn't destroy a single unique or wonderous building. Unless you're a RPer like many of us here.
