Requirements for Hall of Unity?

Published on Sunday, November 19, 2023 By Robert_Olesen In Galactic Civilizations IV

The requirement for Hall of Unity says "You must control at least 3 worlds". That's ambiguous. 

I suppose World = Core world. Is that correct?

I have 4 core worlds (my own, not conquered) and none of them have the Hall of Unity in the build list. Does control mean conquer? Do I need to conquer three (core?) worlds to be able to build the Hall of Unity?
