Themyscira

Themyscira (also referred to as Paradise Island) is an island where the mythical Amazons live in DC Comics' Wonder Woman series, and where Wonder Woman herself was born, being the daughter of the queen Hippolyta. The island itself is protected by the Olympian gods, and on that island the Amazons remain young for as long as no other human (particularly males) step forth on it.
