Province improvements
This article is accurate for the latest versions of EU3, Napoleon’s Ambition, In Nomine, Heir to the Throne and Divine Wind.
Province improvements are structures that serve an administrative, military or trade purpose on a provincial level. In game terms, these are represented by constructions that can be built in individual provinces assuming a tech level and cost requirement are met. They come in three forms: buildings, fortifications and manufactories. Province improvement costs, prerequisites and effects can be found in buildings.txt while the required technology levels can be found in the respective tech files.
Note that besides the effects listed here, the presence of some buildings also influence the supply and demand of certain trade goods. These effects are listed here.
In Divine Wind
The building system is completely reworked in the Divine Wind expansion. All buildings now require a magistrate to build beside money. Many new buildings have been added, some of which where provincial decisions in previous versions, like the canal.
There are now three categories of buildings: normal buildings, manufactories and unique buildings. Manufactories have not changed from Heir to the Throne, except that they cost a magistrate as well. Unique buildings can only be build once in a country, sometimes only when special requirement are met. An example of a unique building is the War College, which no longer needs to be build in the capital.
Normal buildings are all the other buildings. These are grouped into one of five categories, corresponding to the branches of the tech tree: Government, Production, Trade, Naval and Land. There are six buildings in each of these five categories, each with a level. Any building besides level 1 buildings requires that the building of the previous level is present in the province before it can be build. Lastly, it is only possible to build one level 5 and one level 6 building in a province. The presence of any level 5 building will grey out the buy button of any other level 5 building, forcing the player to specialize his provinces.
All buildings except forts of level 1-4 and manufactories are automatically removed when the province changes ownership, unless the new owner has a core on the province.

Manufactories
Manufactories give the following benefits:
- A 6 per year bonus to local income. This is doubled in provinces with a bonus resource (see table). The bonus from university and fine arts academy is never doubled.
- A monthly 5 technology investment bonus to one branch of the tech tree.
- An increase the population growth of their province by 1%.
Manufactory costs begin at 1000 and increases proportional to the amount of manufactories you build. All manufactories have a construction time of 60 months and like all buildings in Divine Wind require a magistrate. Only one manufactory can be built per province.
There are generic missions for each manufactory to build one.
| Manufactory | Tech Investment | Bonus Resources | Tech Level | Additional Effects |
|---|---|---|---|---|
| Refinery | Trade | Wine or Sugar | Trade 14 | None |
| Naval equipment manufactory | Naval | Naval Supplies | Naval 15 | None |
| Weapons manufactory | Land | Copper or Iron | Land 15 | None |

In Nomine and Heir to the Throne
Buildings and Fortifications
Buildings have effect on a provincial level only, meaning their improvements apply only to actions undertaken in the province they are present in. All buildings, except the War College and Admiralty, can all be built in a single province, assuming the technology and price requirements are met.
Forts are key to holding provinces in Europa Universalis. Without a fort, an enemy or rebel army will immediately occupy a province. If a fort exists then a siege begins. If you have a province without a fort, it is advisable to have some troops stationed there. Your troops will give you some time to respond with reinforcements without losing control of the province. Your provinces without forts can be vulnerable to unexpected revolts.
The garrisons inside forts do not cost military maintenance and do not count towards your nations forcelimit. If a fort is successfully taken, it will begin with a garrison of 100 soldiers. Each month the garrison will increase up to the garrison limit without drawing on your manpower. Forts can be removed via the Fortification neglected event when the Offensive/Defensive slider is towards the Offensive side.
In In Nomine and Heir to the Throne, the effectiveness of your forts is modified by your province's defensiveness. Defensiveness increases the time between siege checks, and increases the effective fort level of your fort.
Note: The effects of forts are cumulative. The values given are the sum of those effects (e.g. Fort Level 2 does not give an additional 2000 to the garrison but adds 1000 to the Fort Level 1 garrison value).

Manufactories
Manufactories give a 6 ducat bonus to local income plus a 5 ducat contribution to certain technology investments. The local bonus for all but the University and Fine Arts Academy is doubled to 12 ducats with the presence of certain resources.

Unlike buildings, you may only build one manufactory per province.
