The modern history of what became known as the city of Atlantis originates in a ranch called Mulberry Farms, owned by Philip D. Lewis, a former Florida state senator.

In 1958, real estate developers Nathan Hunt and Paul Kintz purchased the land, and began the construction of what became a gated golf and country club community.

The residential development, combined with a small amount of adjacent land for commercial use, was incorporated on June 19, 1959.
