Boskednan stone circle is a partially restored prehistoric stone circle near Boskednan, 6.4 kilometres northwest of the town of Penzance in Cornwall. The megalithic monument is traditionally known as the Nine Maidens or Nine Stones of Boskednan, although the original structure may have contained as many as 22 upright stones around its 69-metre perimeter.
The stone circle once probably consisted of 22 granite blocks, from which 10 still survive. Six stones stand upright, one sits half a metre out of the ground, the others remain lying in the soil. The stones are all about 1 m high, the highest measure approximately 2 m and stand to northern edge of the circle. The stone circle originally described a circle with a diameter of approximately 22 m. The stone circle may have belonged with the nearby barrow to an extensive cult district.
Stone circles such as that at Boskednan, were erected in the late Neolithic or in the early Bronze Age by representatives of a Megalithic culture.
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.
