The remains of the château de Bar-sur-Seine are the ruins of a medieval French fortified castle, destroyed in the 16th century. The first building was erected in the 13th century, adapted and altered into the 15th century.
The historic importance of the castle was due to its position on the frontier between Champagne (a vassal county of the King of France) and the Burgundy (a duchy allied with the English) during the Hundred Years War. At the time, the château de Bar-sur-Seine was considered the most important in Burgundy. Its architecture is close in style to that of the Château de Peyrepertuse in Aude.
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.
