Cornia Nou is a settlement dating from the Talayotic period (1000-750 B.C.) with two well preserved talayots of different types. The oldest and most spectacular is circular and measures around 26 metres in diameter, an impressive monument. It has a building in the facade with access at ground level; an inside passageway ascends to a set of steps leading up to the upper platform of the talayot.The other talaiot is considerably smaller and has a distinctive feature of a passageway covered with stone slabs crossing its diameter and joined to a wall. Excavation work carried out in 2007 uncovered the remains of pottery items dating from the post-Talayotic period in the 3rd century B.C. Plus, near the site there is a large Islamic necropolis with burial chambers carved out of the rock, which supports the hypothesis that rural settlements from the Muslim period were built on top of the sites from the Talayotic period.
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.
