Gera or Yera (Greek: Γέρα) is a town on the Aegean island of Lesbos in Greece. It once stood as one of the largest ports of the island. According to scholars the ancient name may have been Portus Hieraeus; Pliny the Elder mentions a Lesbian city called Hiera, which was abandoned before his time.
The 1st-century Roman historian and naturalist Pliny the Elder recorded the existence of an ancient city on Lesbos known as Hiera. Scholars argue that the name is derived from the Greek goddess Hera, and there is evidence that the island of Lesbos followed the cult of Hera during the time of Sappho around the 7th century B.C.
