Entremont is a 3.5-hectare archaeological site three kilometres from Aix-en-Provence at the extreme south of the Puyricard plateau. In antiquity, the oppidum at Entremont was the capital of the Celtic-Ligurian confederation of Salyes. It was settled between 180 and 170 BCE, somewhat later than the inhabitation of other oppida, such as Saint-Blaise (7th to 2nd centuries BCE). The site was abandoned when it was taken by the Romans in 123 BCE and replaced by Aquae Sextiae (modern Aix-en-Provence), a new Roman city founded at the foot of the plateau. By 90 BCE, the former oppidum was completely uninhabited.
The site contains two distinct areas of settlement surrounded by ramparts. Archaeologist Fernand Benoit named the older area, on the summit, 'Ville Haute', and the lower 'Ville Basse'. Subsequently it was recognised that the latter was an enlargement of the former, and they are now labelled 'Habitat 1' and 'Habitat 2', respectively.
Finds from the site are displayed at Musée Granet and include statues, bas-reliefs and impressive severed heads.
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.
