The Heartland of the city is filled with farms, much like the outskirts. However, in the middle of the Heartland, on one of the great lakes, the city of Eden was established. Eden is the capitol of Rapture, and while it is significantly smaller than most of the other big cities, it still is the oldest.

Surrounding Eden are many smaller cities, as well as industries. All of these cities eventually give way to suburbs and then to farms, which connect to the outskirts.
