Goward Dolmen is a megalithic dolmen or cromlech situated between Hilltown and Castlewellan The huge granite capstone has slipped from its original horizontal position. The capstone is 4m long and 3m wide, with an estimated weight of 50 tons. The capstone has shifted sideways on its supporting uprights, possibly due to the collapse of the backstone, and now overhangs the chamber on its north side. The unsegmented burial chamber is 9 feet long with an entrance on the east, flanked by orthostats which could be the remains of a crescent shaped facade. Its largest stone is the enormous capstone which has fallen sideways, revealing the megalithic chamber it once covered, in which a cremation urn and a flint arrowhead were found in 1834. Stones standing independently at the eastern side of the monument suggest that it may once have had a forecourt facade like a court-tomb.
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.
