The ancient name of Leonidion is Vrasies or Prasies. It was located at Plaka, where the seaport of Leonidion is situated today. This is where the sea washed up the coffin with the dead body of Semeli and her only son, Dionysus. The devout local people honored Semeli with a burial and placed defenseless Dionysus under the protection of the Nymph Ino.

The port of Plaka became a commercial trading center, distributing merchandise inland and even as far as the regions of south Laconia. For centuries this port connected the harbors and the islands of the Argosaronic Gulf with the coasts of the Myrtoon Sea.

The close ties of the Leonidion community with Constantinople and the Greek cities of the Black Sea led to the social development of our native land.
