The Abbey of La Clarté-Dieu was a Cistercian monastery. The abbey was founded in 1239 by the executors of Peter des Roches, Bishop of Winchester, as one of a pair, the other being Netley Abbey in Hampshire, England. The bishop had conceived the idea of founding a pair of monasteries some years before and had begun collecting the necessary endowments for them, but his death in 1238 prevented him from completing the project. The first monks arrived at the site in 1240.
The abbey was severely damaged in the course of the Hundred Years War and the cost of rebuilding proved a heavy burden on the finances of the community. Nevertheless, La Clarté-Dieu managed to survive until the French Revolution when it was closed and sold off along with all the other monasteries of France. Following the revolution the abbey was for a long time used as a farm and some of the buildings were allowed to fall to ruin. Despite this, much of the mediaeval abbey remains in excellent condition along with some fine post-mediaeval additions. The abbey is preserved as an historic monument and is 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.
