no City Hall
Bronze Working
New settlements that build the Tribe Hut can produce Tribe units. The Tribe Hut gives improved tile production when in Tribalism goverment (no tile penalty). You can replace Tribe Hut with City Hall to increase town influence/vision radius, but at the expense of Tribe Hut bonus.

Prevented by City Hall in the city.

  • The discovery of Bronze Working will make Tribe Hut obsolete.
  • The presence of City Hall in the city will make Tribe Hut obsolete.

Radar
None
Airports allow a city to produce veteran air units (including helicopters and missiles). Damaged air units 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.

Construction
Irrigation
no River
no Lake
None
Allows a city to grow larger than size 8. See Sewer System.

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 10%.

Building an Aqueduct in a city without adjancent tile access to a lake or river requires knowledge of Construction and at least one irrigated tile within city radius. These Aqueducts cost more to build and maintain.

The Bunkers fortification makes it easier to defend a city. They add a 100% bonus to the intrinsic defense strength of units within the city against bombs, missiles and land units (including plunging fire artillery), but are ineffective against airborne and sea units. Bunkers also prevent the loss of population which occurs when a defending unit is defeated, except of attack performed by Air units. Unlike City Walls, Bunkers do not restrict city growth.

no Temple
no Mosque
None
A Cathedral makes 3 unhappy citizens content in a city. The addition of Michelangelo's Chapel (ally great wonder) increases the number of unhappy to content citizens to 6 (e.g. doubles the effect of Cathedral). This makes it easier to maintain order in that city, however it does not affect citizens made unhappy by aggression. The addition of J.S. Bach's Cathedral (small wonder) brings 2 additional luxury points, except when in Communism government.

no Research Lab
None
With a Railway Station present, the Cement Plant increases overall city production by 50%, adds an extra 2 trade points for each coal mine, and 2 shield points for each mine in mountains or desert without resources.
This facility increases significantly the rate of pollution caused by production.

With sufficient shield production, cities with a Cement Plant can produce up to two units each turn, but only a single unit of types which cost population.

Note: Cement Plant requires mountains within city range and cannot be built in a city, where the Research Lab is located.

B.city wallsCity Walls 60
0
Masonry
no Bunkers
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, sea units or plunging fire artillery. City Walls also prevent the loss of population which occurs when a defending unit is defeated, except of attacks performed by Air units or plunging fire artillery.

City Walls need to be dismantled to allow city growth beyond size of 48. For larger cities use Bunkers.

Increases the vision range of the occupied city.

Requires knowledge of the technology Masonry. Prevented by Bunkers in the city.

  • The presence of Bunkers in the city will make City Walls obsolete.

This improvement is mandatory for cities above size 48.


Requires knowledge of the technology Electricity. Requires Water Treatment in the city.

B.granaryGranary 40
1
Pottery
None
The Granary decreases food waste in the city as it grows. When any small city grows or shrinks, 10 food points are saved instead of wasted. This helps cities to grow faster and more easily withstand famine. With a Granary this benefit is extended to cities of size 4 and above. Ten food points is half of 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 Windmill/Watermill/Supermarket it eliminates food waste, except of Despotism where Courthouse is also required.

TIP1: To maximize the speed with which a city grows, you should build a Granary before it grows larger than size 4.

TIP2: Granary is mandatory for Rapture growth under First Republic, Direct Democracy or Legalism governments.

Requires knowledge of the technology Pottery.

B.harbourHarbor 40
1
Seafaring
"Sea" terrain
no Port Facility
None

All ships are repaired 50% faster in a city where Harbor exits.

In case of Thalassocracy goverment, any new Sea unit built in a city with Harbor have Veteran status.

Tip: Port Facility is an improved version of the Harbor.

B.hydro plantHydro Plant 180
4
Turbine
Factory
River
None
Any kind of electrical plant increases the shield production effect of any Factory or Mfg. Plant in its city by 25% each. Thus, an electrical plant in combination with either a Factory or a 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 will 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 (small wonder). 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 Turbine. Requires Factory in the city. Requires River on the tile or an adjacent tile.

Nuclear Power
Factory
None
Any kind of electrical plant increases the shield production effect of any Factory or Mfg. Plant in its city by 25% each. Thus, an electrical plant in combination with either a Factory or a 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 will 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. See 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.

None
Any kind of electrical plant increases the shield production effect of any Factory or Mfg. Plant in its city by 25% each. Thus, an electrical plant in combination with either a Factory or a 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 will lead to the city generating more pollution.
