List of wonders in Civ4

In addition to Buildings, Civilization IV also contains Wonders, which are unique structures that have high production costs, but provide additional gold, culture, or other potent benefits when completed.

While National Wonders are restricted to one per civilization, Great/World Wonders are restricted to one per game. In addition, there are also Projects, which have effects similar to Wonders.
