Church

The Church (and Mosque) is a building in Age of Empires III where European colonies train their healing units, priests, imams or missionaries. It is also a source of many unique upgrades either provided by your civilization or unlocked in your Home City and shipped to the New World. Some civilizations, particularly the Ottomans, get a lot of benefit from the improvements here.

Each colony may build only one church.
