 	Aqueduct 	60
2 	Construction
None 	Allows a city to grow larger than size 8. A Sewer System is required to grow past size 12.
* Allows Sewer System (with Sanitation).
 	Amphitheater 	60
4 	Construction
None 	Entertains citizens: three unhappy become content. (Four after Electricity.)
 	Bank 	80
2 	Banking
None 	With a Marketplace, a Bank increases the luxury and tax production in a city by 100%.
* Allows Stock Exchange (with Economics).
 	Barracks 	30
1 	None
Gunpowder 	Each new land unit built in the city gets +1 veteran status. Damaged land units which stay in town one full turn without moving are healed.
* Obsolete after Gunpowder.
 	Barracks II 	30
1 	Gunpowder
Mobile Warfare	Each new land unit built in the city gets +1 veteran status. Damaged land units which stay in town one full turn without moving are healed.
* Obsolete after Mobile Warfare.
 	Barracks III 	30

 	Cathedral 	75
3 	Monotheism
None 	Makes 3 unhappy citizens content in a city. Theology increases the effect by +1. Communist government reduces the effect by -1.
* Requires a Temple.
 	City Walls 	60
0 	Masonry
None 	City Walls triple the defence of units in a city vs land units. Walls are ineffective against Air & Sea & Howitzers. City Walls prevent the loss of population when a unit is destroyed by land attack.
 	Coastal Defense 	60
1 	Gunpowder
None 	Doubles the defense of units within a city when defending against enemy ships.
 	Coinage 	-
0 	None
None 	Sets a city's shield production to generate gold coins for the treasury.
 	Courthouse 	45
1 	Code of Laws
None 	Reduces corruption in a city by 60% (rounding causes ~50%). In Democracy, makes 1 unhappy citizen content. Makes the revolt cost of the city 4 times higher. Gives +1 shield free unit upkeep. Protects diplomatic units vs. hostile diplomatic units by roughly ⅛. (average base odds of ½ - ⅛ = ⅜) Reduces odds of hostile diplomatic actions by a raw 20%. Eliminates "tile penalties" in Despotism and Anarchy.
 	Ecclesiastical Palace	100 	Mysticism 	Makes a city a second "religious capital" of your government. Corruption in other cities is based on distance from a capital, except in Democracy or Communism. The cost of inciting a revolt also depends upon distance from a capital. Loss of religious capital does not result in civil war or loss of any spaceship. The religious capital gets the same output bonus as the Palace, but renders it in gold instead of shields. In Fundamentalism, Fanatics from this city will also get +1 addition vet level.

3 	Fusion Power 	
*Allows Hydrogen Bomb
*Allows Tactical Nuke
*Allows Doomsday Bomb
 	Factory 	140

Pollution is 25% less than a Power Plant+Factory, and 50% less than a Power Plant+Factory+Mfg Plant. A city can build a Hydro Plant if it is next to (or on) a River tile. Each city may only use one Power/Hydro/Nuclear/Solar Plant.

 	Police Station 	50
2 	Communism
None 	Reduces unhappiness caused by two military units. Protects diplomatic units vs. hostile diplomatic units by roughly ⅛.
