The Civilopedia entries for the War Department, National History Museum, and Royal Society list only one of the previous buildings as being required, but I only just now am able to build them. I haven't been checking regularly, but I just recently entered the Atomic era by researching Rocketry.

A Tier 3 Government.
The plaza is linked to your advancement in the Civics tree, not the Science.
