Itanos was particularly powerful community during the Greek era and it was flourishing by the seventh century BC. Itanos was continuously at war with its neighbours Praisos, and later Hierapytna.
In the 8th century AD Itanos was destroyed in an earthquake but the inhabitants stayed and rebuilt the town. Only in the 15th century after attacks by pirates the town was finally destroyed and deserted. Because the west of Crete slowly elevates upwards and the east odf the island is slowly sinking (6 to 9 meters in the last 2000 years, mainly caused by earthquakes) parts of the harbour of Itanos have now sunk into the sea.
Herodotos was the first Greek historian who mentioned Itanos. The archeological site of Itanos is open to the public. It is possible to see the ruins of houses, city walls and Christian churches. Many Greek inscriptions were found in situ; the most famous one, kept now in the monastery of Toplou, relates a decision by the Roman Senate about Itanos' conflicts and territorial disputes with the neighbor cities Praisos and Hierapytna.
The ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
