—In-game description

The Mosque is an economic building in Age of Empires III that is available to the Ottomans and Hausa. Its primary purpose is to contain technologies that improve the Ottomans' automatic Settler production right from the Exploration Age. It also generates 0.8 XP per second. Secondarily, it also functions as a Church (available to other European civilizations in the Commerce Age), but with the healers named as Imams instead of Priests.

As Ottomans start with a lot of wood and the upgrades are quite powerful, especially in a long game such as Treaty, it can be a good idea to place the Mosque early and obtain the training time upgrades as soon as possible. However, it is not necessary to research the Settler cap upgrades until the appropriate cap is reached.

As the Mosque is available to the Ottomans and Hausa, only their cards and other civilizations' TEAM cards that are shown on the following tables:


Age of Empires III[]

  • The Mosque costs 100 wood, generates 0.4 XP per second, and takes 10 seconds to build.

Definitive Edition[]

The African Royals[]


  • While the Mosque is often referred to and treated as a distinct building available only to the Ottomans and Hausa, the game's data files reveal that it is actually an ordinary Church with its name changed and a distinct appearance.
    • As a result, the Mosque sometimes incorrectly plays church bell sounds like the regular Church would, rather than adhans or Quran recitals.


A Mosque is a place of worship for people of the Islamic faith. The first Mosque was located in the holy city of Mecca. Followers of Islam, called Muslims, are required to pray five times a day. It is preferable that these prayers be performed in a mosque, but they can be performed anywhere if there is no mosque nearby.
