Mill (Age of Empires III)

The Mill is a building in Age of Empires III that provides a steady source of Food, but not at a rate per Settler/Villager higher than hunting without direct upgrades, Home City cards, and native settlement improvements.

Up to 10 Settlers can work on a Mill at once, though due to collisions between units it is best to only use 7 per structure. Mills placed too closely together (side by side with no space between them) may cause some Villagers to "migrate" to the adjacent Mill; this bug occurs with Plantations and Rice Paddies as well.

Mills replace the role of Farms in earlier games in the series. However, Farms are reintroduced in The WarChiefs, acting as the Native American version of a combined Mill and Livestock Pen.

History
"A mill is used to break grains down into smaller pieces making cooking and baking easier. They were historically powered by wind, water, or livestock. Grain is ground between stones, known as millstones, until it is fine enough to be used for whatever purpose is needed. Flour for bread was made in this manner."
