The moat and round tower of Pencoed Castle may date from 1270 by Sir Richard de la More. It passed to the Morgans of Tredegar in the 15th century and a big new mansion on the east side and the gatehouse on the west side were built by Sir Thomas Morgan in c. 1490-1500. The gatehouse and corner tower are ruined and the mansion lies in a gutted and derelict state, though still with some flooring and the roof more or less intact.
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.
