The Antequera Dolmens Site is a cultural heritage ensemble comprising three prehistorical monuments: the Dolmen of Menga, Dolmen of Viera and Tholos of El Romeral. It was declared a World Heritage Site in 2016 together with two natural mountain features (the Peña de los Enamorados and El Torcal).
Built during the Neolithic and the Bronze Age out of large stone blocks that form chambers and spaces with lintelled roofs (Menga and Viera) or false cupolas (El Romeral), and used for rituals and funerary purposes, the Antequera megaliths are widely recognised examples of European Megalithism. The megalithic structures are presented in the guise of the natural landscape (buried beneath earth tumuli) and their orientation is based on two natural monuments: La Peña de los Enamorados and El Torcal. These are two indisputable visual landmarks within the property.
The Neolithic Dolmen of Menga represents one of the most important masterpiece of megalithic architecture (Atlantic tradition) based on post-and-lintel construction with an earthen covering, notable for its enormous dimensions that push the size possible in a corridor sepulcher by incorporating the unprecedented solution of intermediate pillars; likewise, the later, Chalcolithic tholos (beehive tomb) of El Romeral complements the two dolmens with its corridor and false dome of drystone masonry (Mediterranean tradition).
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.
