In Civilization VI, buildings are no longer trapped in your City Center, but may sprawl across your territory as part of districts. The map is more important than ever as you are faced with important strategic placement decisions. The Campus and Holy Site each receive special boosts from placement near Mountain tiles, but the Campus also benefits from a nearby Rainforest tile.

A city must expand its Population before it can construct multiple districts:
• 1 Population for 1 District
• 4 Population for 2 Districts
• 7 Population for 3 Districts
• Each additional District requires +3 Population
The Aqueduct, Neighborhood, Spaceport, Dam, and Canal districts ignore this Population requirement. Districts which require a certain number of Population are specialty districts.

When a city is ready to construct something, the Choose Production button will appear. If a district can be constructed, it will appear on this menu. Click on the district to order the city to begin construction, opening the district placement lens. Here, you will be given an overview of the different yield outcomes available on the tiles surrounding your City Center, and you can better make a decision about where to place your district. This lens will also show you which tiles are unavailable, as some districts have very specific placement requirements (for example, the Encampment cannot be built adjacent to a City Center). Furthermore, all districts must be built within 3 tiles of a City Center.

Districts may be placed on top of features such as Woods or Rainforest if you have the technology to remove those features, but for a longer construction time. No District can be built on a floodplain.
