A series of 5 buildings, known as "national projects", are also available to be built. Note, however, that national projects may be built only around your capital and so you should be careful when constructing them. They are:
- Nobles' Palace - allows for the researching of different abilities.
- State Bank - full abilities of colossus
- Military-Industrial Complex
Most factions will be able to build a State Bank in the Industrial Era, as well as another national project. Each faction has a unique secondary national project, which serves to balance out game issues.
