Château de Castelnoubel is situated on a promontory overlooking the Mondot valley near Bon-Encontre. The site where the castle stands has been occupied since the 10th or 11th century. Construction of the current castle began in the late 13th century. It belonged to the Marmande family initially, with Arnaud de Marmande being the first known lord. The Durfort family took ownership after the Marmandes, with Arnaud de Durfort receiving jurisdiction rights from Charles le Mauvais, King of Navarre. The Durforts continued to hold Castelnoubel until the late 16th century, when it passed through marriage to the Secondat family.
In the early 18th century, Castelnoubel came into the possession of Louis Pascault de Poléon and remained in the Pascault de Poléon family until the 19th century.Pierre Loubat and later Joseph-Marie-Étienne Giraud, who served as secretary general of the prefecture of Agen, were subsequent owners.The castle eventually became a historic monument in 1966.
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.
