Valmont Abbey (Notre-Dame-du-Pré de Valmont) was a Benedictine abbey founded in 1169 by Nicolas d'Estouteville with Benedictines split off from Hambye Abbey. It never held more than 25 monks and was destroyed and rebuilt several times, with the abbey church only truly completed in the 16th century – countess Marie II of Saint-Pol is buried in it.
The abbey buildings were built from 1678 to 1782 under Louis de La Fayette (1634–1729), commendatory abbot, who tried to introduce the Saint Maur reforms to the abbey. It was finally reformed in 1754 by the Maurists and was rebuilt during the second half of the 18th century, until the French Revolution, when it was dissolved – its monks were dispersed in 1789 and its buildings sold off to private owners in 1791.The painter Eugène Delacroix often holidayed at the Valmont manor house and the abbey ruins inspired his drawing Ruines de l'abbaye de Valmont, now in the musée du Louvre. The abbey became a monastic site again in 1994, re-founded by Benedictines from Notre-Dame-du-Pré at Lisieux and re-dedicated in 2004.
Its chapel and surviving ruins of other parts of the abbey were classed as a historic monument in 1951 and the facades and roofs of all the abbey buildings were made historic monuments in 1965.
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.
