The Town Center in Age of Empires III is the starting building for a colony and acts as the default Home City drop-off point. Town Centers can train Settlers/Villagers, call in one levy of Minutemen, and can advance to the next Age. Only the Explorer or a Covered Wagon can build a Town Center and each player is limited to only one before Fortress Age which after that increases to three. The Portuguese receive a free Covered Wagon every time they Age up until the Industrial Age and together with some Home City shipments can have the maximum increase to six Town Centers.
