A Wonder is a mega-building, which may be unique in the world, and provides exceptional bonuses. All Wonders are inspired by real-world buildings and landmarks. Note that the effect of each wonder only applies to the civilization controlling the city where it is built; also, many Wonders have on-build effects which won't activate again if another civilization captures their city. This page lists all World and National Wonders available in Civilization V, as well as Projects.
