Atlantis

Atlantis is an island city. It is said to be the sort of place one never wants to leave. While its Earth-1 counterpart is considered a "lost city" due to it seemingly being submerged in the ocean, this Atlantis is above water.

History
Jay Garrick admitted to loving Atlantis, especially as one of his best friends originated there. Later, Harrison Wells opened a map of his world. A large island, presumably Atlantis, was visible west of Europe.
