Projects
City Projects are produced directly by a city, using its civics output per year. Projects are located within the city center tile and affect the overall yields of the city (in contrast to Improvements, which are built by Worker units on the map). The effects of completing a project may vary depending on nation and Archetypes of the Leader & Governor of the city. Most projects have stronger variants for every cultural level. Some projects are freely repeatable, others are permanent and cannot be produced again in the same city until it reaches the next cultural level.
Permanent projects
Permanent projects can only be done once. When a city reaches the next cultural level, it may produce the stronger variant of the project, replacing the effects of the previous one (i.e., when completing Treasury II a city gains a net of +10 per year).
Treasury
Treasury projects are mainly used to increase the city's money output. If playing as Babylonia, every treasury project also provides +2 per year in the city. If adopted Professional Army law, every treasury project also provides +2 per year.

Other Permanent Projects
There are unique projects that cannot be enabled through the technology tree, but rather through certain Events. These projects are automatically installed in the city, without investing time and resources.
Repeatable Projects
Repeatable projects may be produced by the same city more than once before it reaches its next cultural level (enabling the stronger variant of the project). Permanent effects from the different tiers of these project (excluding Council & Decree) stack, in contrast to Permanent projects which replaces the effects of the previous tier. Repeatable projects cost no resources to produce.
Council
Council projects are different in that they always take 1 turn to build and their effects (increase in civics & money output) last only for one turn.
Name | Requirements | Construction cost | Effects |
---|---|---|---|
Council I | Cultural level: Weak | ||
Council II | Cultural level: Developing | ||
Council III | Cultural level: Strong | ||
Council IV | Cultural level: Legendary |
