This article is about the buildings in Age of Empires II. For the armor class, see Armor class: Building. For buildings in other games of the series, see Building. |

The constructable buildings of Age of Empires II are best divided into the Age where they become available or by use. Some buildings are unconstructable, and are only found in the Scenario Editor or provided beforehand in a scenario, and cannot be built by the player in any regular game.
The appearance of the buildings is the same for all civilizations in the Dark Age, but splits in different architecture sets for various groups of civilizations from the Feudal Age on.
