By placing wonders next to the district that they play into, you can also earn yourself even more boosts. They'll now take up a full tile within your city, and remove any resources, food, or production that previously lived in there. Instead of just appearing within the borders of your city, you'll now have to decide specifically where you want to place them. Building a science district next to the mountains, or a Faith district next to a river, will give you immediate boosts. Some cities will get boosts from the world around you, depending on where districts are placed. These include industry, culture, science, faith, trading, and more. You'll need to weigh which district is most important to your Civilization. However, every city is not going to have the room for every district that is available.

You'll need these districts in order to properly grow your cities.
