Feitoria

The Feitoria (Portuguese: Factory) is a unique economic building available only to the Portuguese in the Imperial Age. It generates all four resources (food, gold, stone and wood) without the need of Villagers. The building costs 250 wood and 250 gold and requires 20 population. The building is very durable with high armor and a base 5200 HP, the most of all buildings. It also ties with the Wonder as the largest building, taking 5x5 tiles.

Tactics and Placement
There's no limit to how many Feitorias a player can build other than the population limit. Players can still build one as long as they have at least one population headroom (queued units will count against this headroom).

It will generate each of the four resources over time at the rate of 0.7 resource per second (less for gold and stone). While it is not seemingly worth the population space, it is difficult to place a numeric value on the generation of gold and stone.

The Feitoria is most suitable for late game when resources become scarce, especially stone and gold. Players must be sure to place it in well defended areas in order to protect its slow trickle of resources.

Conversion
Non-Portuguese players can manage to procure their own Feitorias as long as they can research Redemption at the Monastery as the structure does not have conversion protection. The Feitoria's population space of 20 will be imposed on the player. Portuguese also can research Heresy, in which case the structure will be destroyed instantly when converted.
