Below is the list of all city buildings in Sid Meier's Civilization IV.

The icon after the building represents the game version, when that building was introduced. C4w means Sid Meier's Civilization IV – Warlords and C4bts means Sid Meier's Civilization IV – Beyond the Sword. Where no icon is displayed, that building comes from the base game.

Every information comes from the latest patches: Civ4 1.74, C4w 2.13 and C4bts 3.19.
