Built around 1150 by Guy III le Bouteiller de Senlis, Château de Montépilloy dominates the county of Senlis, thanks to its formidable keep, probably the highest of the royal domain at the time of its construction (around 1190-1200).
Testimony of a prestigious medieval past, the remains of the fortified castle include, in addition to the keep, an enclosure with a polygonal moat, an entrance gate through which one accesses the farmyard, a curtain wall with machicolation connecting the keep to the stately home and its semi-circular flanking tower.
The castle and its seigneury belonged to a succession of historical figures, each close to a king of France. The castle is open to the public
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.
