Airport
1203
Radio
----
None
Allows a city to produce veteran air units (including helicopters and missiles). Also, damaged air units (again, including helicopters) which stay in town for one full turn without moving are completely restored.
Two cities with Airports can airlift one unit per turn (including aircraft). Airlifting instantly transports the unit from one city to another and will use all of the unit's movement points. A unit must have some movement points left to be airlifted, and cannot carry cargo.
Requires knowledge of the technology Radio.
Aqueduct
601
Constructionno Riverno Lake
----
None
Allows a city to grow larger than size 8. (A Sewer System is required for a city to grow larger than size 16.)
These larger cities enjoy increased defense (+50%) against both land and sea units; however, such large settlements have a small risk of fire, which can destroy buildings in the city.
Starting at size 5, growing cities incur an increasing risk of plague due to overcrowding; an Aqueduct reduces that base chance by 30%.
Building an Aqueduct in a city without access to a lake or river requires knowledge of Construction, and it costs more to build and maintain.
Requires knowledge of the technology Construction.
Prevented by River on the tile or any adjacent tile.
Prevented by Lake on the tile or any adjacent tile.

A Cathedral makes 3 unhappy citizens content in a city, making it easier to maintain order in that city; however, it does not affect citizens made unhappy by aggression. Knowledge of Theology increases the effect of a Cathedral, making an additional unhappy citizen content, except under Communism.
Requires knowledge of the technology Monotheism.
Requires Temple in the city.
* Allows Michelangelo's Chapel (with Monotheism).
City Walls
300
Masonry
----
None
City Walls make it easier to defend a city. They add a +100% bonus to the intrinsic defense strength of units within the city against land units (that is a two-thirds increase for small cities, or a one-half increase for cities larger than size 8), but are ineffective against airborne and sea units. City Walls also prevent the loss of population which occurs when a defending unit is defeated by a land unit.
Requires knowledge of the technology Masonry.
Coastal Defense
601
NavigationOceanic terrain
----
None
Gives a +100% bonus to the intrinsic defense strength of units within a city when defending against enemy ships. For small cities the defense strength is doubled by this improvement; for cities larger than size 8, it is increased by two-thirds.

Entertains the citizens of a city, making 3 unhappy citizens content. (Four after the discovery of Electricity.) However, it does not affect citizens made unhappy by military activity.
Requires knowledge of the technology Construction.
Courthouse
601
Code of Laws
----
None
Halves all kinds of waste in a city (corruption, production waste, and food waste). In your capital, corruption and production waste is eliminated. A Granary together with a Courthouse in a city will eliminate food waste.
Also makes one unhappy citizen content (unless that citizen is unhappy about military activity).
A city with a Courthouse cannot be incited to revolt.
Requires knowledge of the technology Code of Laws.
* Makes it impossible to do the action 'Incite a Revolt' to its city.
* Makes it impossible to do the action 'Incite a Revolt and Escape' to its city.
Factory
1403
Industrialization
----
None
Increases the shield production in a city by 25%, or 50% with an electrical plant of any kind in the same city.
This increase in production may contribute significantly to pollution; a Factory also increases the pollution caused by the population of the city.
Requires knowledge of the technology Industrialization.
* Allows Hydro Plant (with Electronics and River).
* Allows Mfg. Plant (with Plastics).
* Allows Nuclear Plant (with Nuclear Power).
* Allows Power Plant (with Refining).

Granary
401
Pottery
----
None
When any small city grows or shrinks, 10 food points are saved; this helps cities to grow faster and more easily withstand famine. With a Granary this is extended to cities of size 4 and above. (10 food points is half what a small city needs to grow, but more points are needed for later growth steps.)
A Granary also halves the food wasted in cities far from your capital. Together with a Courthouse it eliminates food waste.
TIP: to maximise the speed with which a city grows, you should build a Granary before it grows larger than size 4.
Requires knowledge of the technology Pottery.
Harbor
401
Seafaring"Sea" terrain
----
None
Gives one extra food resource on all Ocean or Deep Ocean tiles (but not Lakes). The city needs to be coastal (next to one of these tiles) to build this improvement.
Requires knowledge of the technology Seafaring.
Requires terrain with the "Sea" flag on the tile or an adjacent tile.
Hydro Plant
1804
ElectronicsFactoryRiver
----
None
Any kind of electrical plant increases the shield production effects of any Factory or Mfg. Plant in its city by 25% each. Thus, an electrical plant in combination with either a Factory or Mfg. Plant gives a 50% production bonus over the level without any of these improvements; an electrical plant, Factory, and Mfg. Plant together give a 100% production bonus. The extra production may lead to the city generating more pollution.
However, a Hydro Plant also reduces the pollution associated with shield production to 50% of its normal value, or 25% in combination with a Recycling Center; pollution is reduced further for the player who owns the Hoover Dam. (A Hydro Plant's effect is the same as that of a Nuclear Plant; with the Hoover Dam, its effect is increased to that of a Solar Plant.)
In each city, only one Power Plant, Hydro Plant, Nuclear Plant, or Solar Plant can take effect at any one time.
Requires knowledge of the technology Electronics.
Requires Factory in the city.

Mfg. Plant
2204
PlasticsFactory
----
None
Increases the shield production in a city by an additional 25%, or 50% with an electrical plant of any kind in the same city; this effect is cumulative with that of a Factory.
With sufficient shield production, cities with a Manufacturing Plant can produce up to two units each turn (but only single units of types which cost population).
This increase in shield production may contribute significantly to pollution; a Manufacturing Plant also increases the pollution caused by the population of the city.
A Manufacturing Plant also has a small risk of suffering an industrial accident, which can lead to pollution and reduce the city's population.
Requires knowledge of the technology Plastics.
Requires Factory in the city.
Nuclear Plant
2402
Nuclear PowerFactory
----
None
Any kind of electrical plant increases the shield production effects of any Factory or Mfg. Plant in its city by 25% each. Thus, an electrical plant in combination with either a Factory or Mfg. Plant gives a 50% production bonus over the level without any of these improvements; an electrical plant, Factory, and Mfg. Plant together give a 100% production bonus. The extra production may lead to the city generating more pollution.
However, a Nuclear Plant also reduces the pollution associated with shield production to 50% of its normal value, or 25% in combination with a Recycling Center. (Its effect is the same as that of a Hydro Plant.)
A Nuclear Plant has a small risk of suffering a nuclear accident, which can lead to fallout and reduce the city's population.
In each city, only one Power Plant, Hydro Plant, Nuclear Plant, or Solar Plant can take effect at any one time.
Requires knowledge of the technology Nuclear Power.
Requires Factory in the city.
Offshore Platform
1203
MiniaturizationOceanic terrain
----
None

Offshore Platforms also increase the pollution caused by the population of the city.
Requires knowledge of the technology Miniaturization.
Requires Oceanic terrain on the tile or an adjacent tile.
Palace
700
None
----
None
Makes a city the capital and the center of your government. Waste in other cities (corruption, production waste, and food waste) is often related to how far away from the capital they are. On top of this, corruption and production waste in your capital itself is half of what it would otherwise be (and a Courthouse will eliminate it entirely).
The cost to enemy Diplomats and Spies of inciting a revolt in a city also depends upon the city's distance from the capital (under all forms of government). Your capital city itself cannot be incited to revolt, and enjoys a bonus when enemy agents try to evade your own agents stationed in the city, or sabotage your buildings.
Take good care of your capital, as its loss may result in your empire plunging into civil war. Losing your current palace also results in losing whatever spaceship you might have.
If the capital is in a dangerous location, or a more central capital would give a better corruption distribution, you can move your palace by rebuilding it in another city.
Under Despotism the city containing the palace gains a +75% gold bonus, and under Monarchy a +50% gold bonus.
* A 'small wonder': at most one of your cities may possess this improvement.
* Makes it impossible to do the action 'Incite a Revolt' to its city.
* Makes it impossible to do the action 'Incite a Revolt and Escape' to its city.
* All players start with this improvement in their first city.
* If you lose the city containing this improvement, it will be rebuilt for free in another of your cities (if the 'savepalace' server setting is enabled).
Ecclesiastical Palace
1400
Theology
----
None
Makes a city the ecclesiastical capital, that acts as a second center of government.
Waste in other cities (corruption, production waste, and food waste) is related to how far away from the nearest capital they are. On top of this, corruption and production waste in the capital itself is half of what it would otherwise be (and a Courthouse will eliminate it entirely).
The city where this palace is located cannot be incited to revolt, and enjoys a bonus when enemy agents try to evade your own agents stationed in the city, or sabotage your buildings.
Under Despotism the city containing the palace gains a +75% gold bonus, and under Monarchy a +50% gold bonus.
Requires knowledge of the technology Theology.
