The Royal Abbey of St. Vincent was a former monastery of canons regular in Senlis, Oise, which was dissolved during the French Revolution. Late in their history, they became part of a new congregation of canons regular with the motherhouse at the Royal Abbey of St Genevieve in Paris, known as the Genofévains, widely respected for their institutions of learning.
The abbey was founded in 1065 by Queen Anne of Kiev, the widow of King Henry I of France, possibly built on the ruins of an ancient chapel dedicated to St. John the Baptist which had been destroyed in the course of invasion by the Normans in the late 900s. King Philip I of France later declared it to be a royal abbey, independent of all authorities, both ecclesiastical or civil, and made a number of grants of land to the community.
The abbey flourished between the 12th-14th centuries. During this period, the abbey went to great efforts to maintain its independence from the local authorities.
The decline started from the 16th century when there were internal disputes. Anyway the commendatory abbots continued to care for the abbey throughout the rest of its history. They made improvements in the walls and buildings until the mid-18th century. The coming of the French Revolution put an end to its life. In 1791, the canons were assembled and ordered to vacate the abbey, in compliance with the suppression of all religious houses under the new laws of the Republic.
The buildings were seized by the revolutionary government and used in various ways, from a military hospital to a prison for prisoners of war. In 1804, the complex was rented to a manufacturer. By 1835 they had fallen into the hands of a developer who had slated the walls and building for demolition. The following years, three canons of Beauvais were able to raise the funds to purchase the property. They then opened a school for boys.

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.
