The necropolis of Li Muri is an archaeological site located in the municipality of Arzachena. The necropolis, thought to be a product of the Arzachena culture and dating from the second half of the fourth millennium BC, is composed of five stone cists. Four of the cists are surrounded by stone circles that originally marked the limits of the mound of earth and rubble that was erected over the burial.
Bodies were interred inside the cists, probably individually (unlike in the rest of Sardinia where the graves were usually collective). The dead were accompanied by grave goods including pottery, stone vessels, hatchets and beads necklace of steatite and gemstones.
The architecture of the necropolis shows strong similarities with contemporary sites of Corsica, Provence and the Pyrenees.
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.
