Poliochne, often cited under its modern name Poliochni, was an ancient settlement on the east coast of the island of Lemnos. It was settled in the Late Chalcolithic and earliest Aegean Bronze Age and is believed to be one of the most ancient towns in Europe, preceding Troy I. Anatolian features of the earliest layers were affected by cultural influences from Helladic Greece, about the start of Early Helladic II, ca. 2500 BC.
The site, with houses huddled together sharing party walls, was unearthed by excavations of the Italian School of Archaeology at Athens (Scuola archeologica Italiana di Athene), beginning in 1930. It is believed that Troy was its main rival commercially; a rivalry that led to the decline of Poliochne circa 2000 BC.
Following initial soundings, regular campaigns at Poliochne were undertaken under A. Della Seta in 1931-36, when they were suspended. Following Della Seta's death, excavations were resumed in 1951-53, 1956 and 1960.
During 1994-1997, Greek archaeologists discovered a more recent Bronze Age settlement on the tiny uninhabited island of Koukonesi situated in the Moudros harbour, west of Poliochne. This settlement was developed circa 2000-1650 BC, and the findings again prove commercial ties with Asia Minor, and with Aegean islands and mainland Greece. Mycenaean ceramics of the 13th century BC found on Koukonesi could prove that, around when the traditional era of the Trojan War took place, the Greeks had a permanent settlement there, rather than just a commercial outpost, understanding the importance of the straits connecting the Aegean and the Black Sea.
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.
