When can citadels be built?

[Stargazer]

I am trying to create a citadel from the console but it is not available.

The pop is above 9000. :book:

So why doesn't it work?

I am using a mod. My appologies.

:embarassed:

If you haven't changed that in your mod (not that I would know how to do that), then the population requirement would be 9600 to build a citadel.
