Construction of Château de Mérens castle dates from the end of the 13th and beginning of the 14th centuries. It was altered in the early 17th century.
The hub of the castle corresponds to the original Gascon structure; the south west square tower belongs to this period of construction. At the start of the 17th century, the castle was furnished with a new system of defence, including a round walk. At the same time, windows were added and the internal layout altered. In the west elements of the mediaeval enceinte can be seen in the wine cellar. Works carried out between 1604 and 1613 concentrated on providing windows and on doubling the height of the east façade. The castle was later converted for agricultural use.

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.
