Château de Quillan was first mentioned in 1125. There had been a fort built by Visigoths already in 781 AD. The castle was conquered by the Royal army of France in 1210 during the Albigensian Crusades. The castle got its current appearance in restorations of 1232 and 1341. Since then Quillan castle has been damaged in wars by Spanish Armies and Huguenots (1575).
Since the 18th century Château de Quillan was left to decay and dismantled. Today still the impressive ruins remain overlooking the village.
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.
