Château de Rouen was a castle built by Philip II of France from 1204 to 1210 following his capture of the duchy from John, duke of Normandy and king of England. Located outside the medieval town to its north, in a dominant position, it played a military role in the Hundred Years' War and the Wars of Religion. It was the main seat of power, administration and politics in the duchy of Normandy for nearly 400 years.
It was here that Joan of Arc was imprisoned in December 1430 and tried from 21 February to 23 May 1431. Vulnerable to artillery like other medieval fortresses, all but the keep (now known as the Tour Jeanne d'Arc) was dismantled in 1591 by Henry IV of France. The pointed roof of the keep was added in restoration works beginning in the 1870s. During the Second World War the tower was camouflaged and turned into a bunker by the occupying German forces. It is now 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.
