The Ancient Theater of Thassos is built inside a natural cavity of the hill and leaning against the wall; according to Hippocrates, it must have been built here as early as the 5th century B.C. During the summer, theatrical plays and artistic shows are performed at the ancient theatre. The ascending, especially organized 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. It is worth attending a performance here during the summer. Leaving the theater behind, the path will lead you to the remains of the acropolis and to the temple of Athena, matron-goddess of the town (6th - 5th centuries B.C.).
