Hephaestia was a town of Ancient Greece, now an archeological site on the northern shore of Lemnos. It was named in the honor of Hephaistos, Greek god of metallurgy, whose cult was maintained on the island. It was once the capital of the island (8th to 6th centuries BCE), of which only the ruins remain.
The Greek theater dates from between the late 5th and early 4th century BCE. It underwent reconstruction from 2000 to 2004. The theatre has capacity of 200 people in the main area, and additional 1000 outside.
According to the historian Herodotus, the cities of the island of Lemnos, Hephaestia and Myrina, were inhabited by Pelasgians. These Pelasgians had promised to return the island to the Athenians if on any occasion Athenian ships, pushed by the north winds, managed to arrive in less than nine days from Athens to the island. Many years later, the Athenians under Miltiades the Younger made the crossing in eight days. The Pelasgian inhabitants of Hephaestia left the island but those of Myrina resisted and were besieged until they surrendered, around the year 500 BCE.
References: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.
