Atlantis serves as the base of operations for the main characters, from which they explore other planets through the [[Stargate (device)|Stargate]]. AccordingBased on the [[Ancient Greece|ancient Greek]] accounts of the Lost City of [[Atlantis]], according to the mythology of the show, the city was built by an advanced race known as the [[Ancient (Stargate)|Ancients]], and is the basis for the [[Ancient Greece|ancient Greek]] accounts of Lost City of [[Atlantis]].

Atlantis was built millions of years ago by the [[Ancient (Stargate)|Ancients]]. The city resided in [[Antarctica]] on Earth until five to ten million years ago, when a deadly plague prompted the Ancients to relocate it to the Pegasus galaxy. There, it served as the Ancients' capital as they built a new system of Stargates and seeded many worlds with humans. However, the Ancients' activities gave rise to a powerful new species, the [[Wraith (Stargate)|Wraith]]. With their vastly superior numbers, the Wraith drove the Ancients from their holdings until only Atlantis was left, defended by its powerful shield and a network of armed satellites.<ref name="The Defiant One">{{sgcite|The Defiant One|Atlantis|show=ref}}</ref> The Wraith laid siege to Atlantis for aone hundred years until the Ancients submerged the city, unable to see a path to victory, submerged the city and returned to Earth through the Stargate. There they merged with the native human population, and their accounts of Atlantis gave rise to the classical myth of the Lost City. Atlantis itself lay on the ocean floor, empty and dormant, for ten thousand years.<ref name="Rising">{{sgcite|Rising|Atlantis|show=ref}}</ref>
