The lush green island of the Northern Aegean sea, because of its privileged location and its rich gold and marble resources, was inhabited very early first by the Phoenicians (1600 -1500 B.C.) and then by sailors from Paros (7th century B.C.). Thassos grew very prosperous from the 6th until the 4th century B.C. The monuments of ancient Thassos still surviving at the eastern part of the main town, Limenas, provide irrefutable evidence of this growth. The ancient town of Thassos had two ports, one for war ships and one for commercial ones. In front of the first one is the ancient marketplace of the town surrounded by three great galleries to the NW and SE, while on the NE side you can see the remains of the ancient Court, the Tholos, the warehouses, a small oblique gallery and a Paleochristian basilica. To the east of the marketplace, heading to the acropolis, you will sea the ruins of the sanctuary of Dionysus (5th century B.C.) and a little further the one of Poseidon (4th century B.C.). The ascending, especially configured path will lead the visitors to the ancient theater (5th century B.C.) offering a unique view of the sea, which was transformed into an arena during the Roman period. Leaving the theater behind, the path will lead you to the ruins of the acropolis and to the temple of Athena, matron-goddess of the town (6th - 5th centuries B.C.). Finally, visitors should definitely pay a visit to the recently renovated Archaeological Museum of Thassos, the collection of which comprises of remarkable findings such as “Kriophoros Kouros” (male statue), Venus and the dolphin, Dionysus head etc.
