The Ancient Agora of Classical Athens is the best-known example of an ancient Greek agora (central public space in ancient Greek city-states), located to the northwest of the Acropolis and bounded on the south by the hill of the Areopagus and on the west by the hill known as the Agoraios Kolonos, also called Market Hill. The Agora's initial use was for a commercial, assembly, or residential gathering place.
Agora contains several remains of ancient temples and buildings. Temple of Hephaestus is one of the best-preserved Greek temples, built around 450 BCE. The excavations has uncovered most of the over 30 known major buildings from the Agora, along with thousands of artifacts. Conservation efforts have restored thousands of pieces of pottery and amphora (the standard storage vessel of the ancient world), studied thousands of marble statues and reliefs, and analyzed the remains of human and animal bones to give us a better understanding of what life was like in the ancient Athenian world.
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.
