Halangy Down is a prehistoric settlement located on the island of St Mary's, in the Isles of Scilly. The ancient site covers the lower slope of Halangy Down hill, overlooking the coastal inlet between the island of St. Mary's and Tresco Island. On the site are the remains of an Iron Age village, two entrance graves, prehistoric field systems, standing stones, post-medieval breastworks, and a Victorian kelp pit.
Archaeological excavations have revealed that the first stone structures were built during the Iron Age (800 BC - 100 AD). Evidence shows that the buildings were continually altered and replaced over the 500 year period of occupation, from the later Iron Age to the Roman period of occupation in Britain (43 AD - 410 AD). The village was made up of a complex of attached stone houses. One house, a large multi-room residence with an interconnecting courtyard, had been built in the Romano-British period. The excavation findings included Iron Age, Romano-British and Anglo-Saxon pottery; flint and quartz tools; a slate spindle-whorl; several millstones; bronze brooches and iron slag.
Near Bant's Carn is a Bronze Age entrance grave located on a steep slope adjacent to Halangy Dwon. The tomb is one of the best examples of a Scillonian entrance grave.
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.
