Wonder (Age of Empires II)

"Building a Wonder of the World demonstrates the superiority of your civilization. Constructing a Wonder that stands for a certain period of time is one way to win the game."

- Age of Empires II description

The Wonder is a civilian building in Age of Empires II that becomes available once the Imperial Age is reached. In certain game modes, the Wonder grants victory if built and defended for 200 years.

Each civilization builds a Wonder of historically relevant and unique appearance. They cannot be converted.

Tactics and placement
Wonders only serve as a victory condition, and as such they must be used only in game modes that allow that kind of victory. When a player starts to build a Wonder, every other player receives a notification with the location of the Wonder so they know where to steer their aggression.

Wonders should be placed in a well defended area so it is better to first build up a strong fortification composed of Castles, walls, and towers, so basically perform a late-game turtling strategy. In any case the player must be prepared to be the main focus of all enemy attacks and prepare to defend the Wonder. It is advised to have a huge army to defend against attacking armies, particularly siege units. Since the Wonder takes incredibly long to be built, it is advised to build it with as many Villagers as possible while also leave them near the area once they finish in case the Wonder needs to be repaired. In team games the support of allies while defending is highly valuable.

It is possible (but costly) to build more than one Wonder so that if one does not stand, other Wonders can stand for the time required to win the game. Although highly unlikely, if multiple players finished their Wonder at the same time, the player in the highest slot regardless of the color wins once the countdown ends.

A Monument (an unconstructable building) can be found in the Scenario Editor and some campaigns. Its appearance varies being different for each civilization, much like the Wonder, and it has the same icon, although it merely functions as decorative. It has 9999 hit points, making it the bulkiest building in the game.

Trivia

 * The Briton Wonder is actually in Germany.
 * The Wonder is the only constructable building that does not have the standard building armor class, along with the Fish Trap.
 * It is the only item in the game to cost three different resources.
 * The Slav Wonder is anachronistic, as the Khizi Pogost was not built until the 17th century. A more accurate choice would've been the Moscow Kremlin when it was a Limestone Citadel, the Dormition Cathedral, or the Ferapontov Monastery.
 * The design for the Malian Wonder is anachronistic by necessity. It is based on the current appearance of the Great Mosque of Djenne, but the mosque was rebuilt in the early 20th century. The original mosque would likely have looked different, but no records exist that describe its appearance, so it remains unknown. The architect for the original mosque was from Egypt, so it is possible that it would have been similar to medieval Egyptian mosques in appearance.

History
"One distinguishing cultural characteristic of the great Middle Age civilizations was architecture. Buildings in Japan, Scandinavia, Britain, Constantinople, and Arabia looked quite different and employed different construction techniques. In many cases, particularly noteworthy buildings stand as icons for the building civilization, marking it for all time as a culture that achieved greatness, if only temporarily. Examples of such Middle Age cultural icons are the Cathedral at Chartres, Charlemagne’s Palace, and the Hagia Sophia at Constantinople."
