Wonders

(This page is for Classic ruleset. For Wonders in the Multiplayer ruleset click here.)

Wonders are special buildings which can each be completed by only one player each game and which often enhance their entire civilization. Once built, a wonder is placed in the city that constructed it, and cannot be sold or destroyed (unless the city is destroyed or changes ownership). However, some wonders are made obsolete by the discovery of a certain advance, and lose their effect. Note the asymmetry: while you must personally achieve the advance required by each wonder to build it, it will be disabled when any player achieves the obsoleting advance.

Here all the wonders are listed, in alphabetical order.

Name	Cost Upkeep	Requirement	Obsolete by	More info
Adam Smith's Trading Co.	400 0	Economics	None	City improvements which would normally have an upkeep of 1 are free of upkeep, for all your cities.
Apollo Program	600 0	Space Flight	None	The entire map becomes permanently visible to the player who owns it -- the player always has up-to-date knowledge of all terrain and cities (but not units) despite fog-of-war. It allows all players to start building spaceship parts (assuming they have researched the necessary technologies).
Colossus	100 0	Bronze Working	Flight	Each tile around the city where this wonder is built that is already generating some trade produces one extra trade resource. The discovery of Flight will make Colossus obsolete.
Copernicus' Observatory	200 0	Astronomy	None	Boosts science production by 100% in the city where it is built.
Cure For Cancer	600 0	Genetic Engineering	None	This stunning technological achievement makes one unhappy citizen content in all your cities.
Darwin's Voyage	300 0	Railroad	None	Charles Darwin's voyage sparked the discovery of the evolution of the species, which inspired greater confidence in science. Gives two immediate technology advances.
Eiffel Tower	100 0	Steam Engine	None	Your reputation and goodwill among other nations is recovered twice as fast.
Great Library	300 0	Literacy	Electricity	The civilization which builds the Great Library gets every advance that at least two other civilizations have achieved. The discovery of Electricity will make Great Library obsolete.
Great Wall	300 0	Masonry	Metallurgy	Works as a City Wall in all your cities. The discovery of Metallurgy will make Great Wall obsolete.
Hanging Gardens	200 0	Pottery	Railroad	Makes one content citizen happy in every city. Makes two extra content citizens happy in the city containing the Hanging Gardens (that is, a total of 3). In the unlikely event where there are no content citizens to get the effect of Hanging Gardens, the wonder applies to unhappy citizens (making them content instead). The discovery of Railroad will make Hanging Gardens obsolete.
Hoover Dam	600 0	Electronics	None	Works as if you had a Hydro Plant in every city. (This reduces pollution and increases the effects of Factories and Mfg. Plants.) Requires the River terrain special. Must be built by a city on or adjacent to a river tile.
Isaac Newton's College	300 0	Theory of Gravity	None	Boosts science production by 100% in every city you control that has a University.
J.S. Bach's Cathedral	400 0	Theology	None	Makes two unhappy citizens content in every city.
King Richard's Crusade	150 0	Engineering	Robotics	Adds one extra shield resource on every tile around the city where it is built. The discovery of Robotics will make King Richard's Crusade obsolete.
Leonardo's Workshop	400 0	Invention	Automobile	Upgrades one obsolete unit per game turn. The discovery of Automobile will make Leonardo's Workshop obsolete.
Lighthouse	200 0	Map Making	Magnetism	Gives all your sea units 1 additional movement point and eliminates the risk of losing Triremes on the high seas. Makes all your new sea units veterans (for all your cities). Requires the Ocean terrain. The discovery of Magnetism will make Lighthouse obsolete.
Magellan's Expedition	400 0	Navigation	None	Gives all your sea units 2 additional movement points. Requires the Ocean terrain.
Manhattan Project	600 0	Nuclear Fission	None	Allows all players with knowledge of Rocketry to build Nuclear units.
Marco Polo's Embassy	200 0	Trade	Communism	The player who owns it gets an embassy with all players. The discovery of Communism will make Marco Polo's Embassy obsolete.
Michelangelo's Chapel	400 0	Monotheism	None	Counts as having a Cathedral in each of your cities. This makes 3 unhappy citizens content in each city. The discovery of Theology increases the effect of a Cathedral, making an additional unhappy citizen content. The discovery of Communism lessens the effect of a Cathedral, reducing by one the number of unhappy citizens made content.
Oracle	100 0	Mysticism	Theology	Makes two of your unhappy citizens content in every city with a temple. The discovery of Theology will make Oracle obsolete.
Pyramids	200 0	Masonry	None	The amount of stored food lost when one of your cities grows or shrinks is reduced by 25%. This helps a city to grow faster and more easily withstand famine. Cumulative with Granary.
SETI Program	600 0	Computers	None	Boosts science production in each city with a Research Lab by 100%.
Shakespeare's Theatre	200 0	Medicine	None	Makes all unhappy citizens content, in the city where it is located.
Statue of Liberty	400 0	Democracy	None	Allows you to choose any government, including those that have not yet been researched by your civilization, and without the transition period of Anarchy.
Sun Tzu's War Academy	300 0	Feudalism	Mobile Warfare	All your new land units start at the first veteran level. The chance of a land unit getting the next veteran level after a battle increases by half. The discovery of Mobile Warfare will make Sun Tzu's War Academy obsolete.
United Nations	600 0	Communism	None	All your units regain two extra hitpoints per turn.
Women's Suffrage	600 0	Industrialization	None	Counts as a Police Station in every city. (That is, for each city, it reduces the unhappiness caused by aggressively deployed military units owned by that city by 2 under Democracy and 1 under Republic -- in other words, it neutralises the unhappiness caused by a single military unit per city. This wonder has no effect under other governments.)
