The temple of Poseidon, the ancient Greek god of the sea, dominates the southernmost tip of Attica, where the horizon meets the Aegean Sea. Perched on the craggy rocks of Cape Sounio, the temple is enveloped in myth and historic facts dated from antiquity until the present times. There are stories about the ship of King Menelaus who stopped briefly at Sounio on his way back from Troy; or about the unfortunate King Aegeus who drowned himself on that spot and the Aegean Sea got named after him; or about the people who built a temple using local marble to honour the god of the sea and safeguard the profits from the neighbouring Lavrio mines.
Laurium or Lavrio or Lavrion is a town in southeastern part of Attica, Greece. It is the seat of the municipality of Lavreotiki. Laurium was famous in Classical antiquity for its silver mines, which was one of the chief sources of revenue of the Athenian state. The metallic silver was mainly used for coinage. The Archaeological Museum of Lavrion shows much of the story of these mines. It is a sea port of much less importance compared with nearby Piraeus. It is located about 60 km SE of Athens, SE of Keratea and N of Cape Sounio. Laurium is situated on a bay overlooking the island of Makronisos (ancient times: Helena) in the east. The port is in the middle and gridded streets cover the residential area of Lavrio.
Rafina is a port town. Its port is the second largest of Attica, after that of Piraeus. Rafina Port is further away from the city centre of Athens than Piraeus, but quite close to Athens International Airport (Eleftherios Venizelos Airport). It is a smaller port mainly serving the southern part of Evvia and the northern part of the Cyclades (Andros, Tinos and Mykonos).
