Tomba dei giganti di Li Lolghi is a burial chamber which probably dates back to the period included between 1800-1200 BCE. Like the tomb of Coddu Vecchiu, it was built in two different phases for different uses: during the Nuragic Age the original Dolmen, high a bit less than 4m and probably belonging to the Bonannaro's culture, was linked to a 10m corridor made up by stones stuck in the ground vertically. This new passageway was the new burial chamber where the dead used to be put in through a small entrance at the bottom of the Dolmen.
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.
