Ballowall Barrow is a prehistoric funerary cairn (chambered tomb) containing several phases of use from the Neolithic to the Bronze Age. It is situated on the cliff top at Ballowall Common, near St Just in Cornwall.
It was first excavated in 1878 by William Copeland Borlase, when it was discovered under mining debris. Reconstruction work which was done after the excavation to make the inside more accessible has further complicated the site. The site today is a confused mix of original and reconstructions introduced by Borlase. The finds from excavations are in stored in museums at Truro, Cambridge and the British Museum.
The construction of the site is unique in consisting of a combination of Neolithic and Bronze Age funerary rituals. A similar site was recorded by Borlase but its location has been lost.
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.
