The necropolis of Sant'Andrea Priu is an archaeological site located on the south side of the fertile plain of Saint Lucia, in the municipality of Bonorva. The complex, one of the most important of the island, is composed of twenty domus de janas; one of them with its eighteen rooms appears to be one of the largest hypogean tombs of the Mediterranean basin.
The necropolis is located on the front of a trachytic outcrop high 10 m and long 180; entrances to the domus are all within a few meters in height from the ground level and some of them are difficult to access because of the detachment of a substantial part of the rock face. The interior of the domus de janas is a faithful reproduction of the houses of that time, with many architectural details (beams, joists, lintels, jambs, pillars and wainscoting perimeter), tending to recreate an environment similar to that where the deceased had spent his existence.
Chronologically, the complex is dated to the Ozieri culture of the Final Neolithic (3500–2900 BC) with partial use and also structural changes of some tombs which continued until the Middle Ages.
Among the domus, three of them, the Tomb of the Chief, the Circular Hut tomb and the Chamber tomb, are of particular importance for their spectacularity and their high degree of conservation.
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.
