Le Dolmen du Mont Ubé is a Neolithic / Chalcolithic () passage grave which was discovered in 1848 by workmen quarrying for stone. The passge leads into bottle shaped chamber that used to have four internal compartments each blocked with low stone slabs. The capstones were taken as well as all but one of the internal compartments. Within the passage stand three stones that may also have had a low sill at some time. These were later used to block of the passage so it could be used as a pigsty.Finds recovered from the workmens spoil heaps included 10 or 12 pots, a Jersey bowl, vase supports, flint and stone tools, stone axes, polished stone pendants and a grape cup (unique to the Channel Islands). Burnt and unburnt human remains were noted in the cists.
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.
