Hautvillers Abbey is a former Benedictine monastery in the Hautvillers commune of the Marne department in north-eastern France. The abbey remained active between 665 and the French Revolution of 1789. It housed the relics of Saint Helena, Empress and mother of Constantine, between 841 and 1819. One of its monks, Dom Pérignon, contributed to the development of sparkling wine in the Champagne region.
The abbey was founded in 650 by Saint Nivard, Bishop of Reims. According to legend, a dove indicated where to build an abbey that would follow the order of Saint Benedict and Saint Columbanus. The abbey flourished under the Carolingian Dynasty and drew great renown thanks to its manuscripts, such as the Ebbo Gospels and perhaps the Utrecht Psalter.
Saint Rieul joined the abbey in 662, before succeeding Saint Nivard as Archbishop of Reims in 669. In 841 a priest from Reims stole the relic of the body of Saint Helena from Rome and the reliquary was transferred to the abbey. The relics attracted pilgrims and the revenues allowed the abbey to purchase lands and vineyards in the vicinity (40 hectares).
The remaining relics of St. Helena stayed in the monastery until the French Revolution broke out. The monastery was destroyed but the cellarer was able to hide the relics until they could be safely transported to Paris for public veneration again. They were then entrusted to the Knights of the Holy Sepulchre and installed in their church, Saint-Leu-Saint-Gilles de Paris,in 1819.
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.
