The Abbey of Munster, also known as Saint Gregory's Abbey was founded around 660. Its purpose was to promote Christianity in the region, which had been in decline since the fall of the Western Roman Empire. It thrived with the support of the Frankish kings, particularly Childeric II and Louis the Pious. Over time, the abbey faced conflicts with the bishops of Basel, Strasbourg, and the emperors of the Holy Roman Empire.
As the region largely turned to Protestantism, the abbey's influence waned. It experienced a revival under Louis XIV, who sent French monks to restore and rebuild the dilapidated buildings. During the 18th century, the abbey became an important regional intellectual center, with figures like Abbot Charles Marchant and theologian Augustin Calmet passing through.
However, the French Revolution led to the dissolution of the abbey and the confiscation and sale of its assets. Some of the convent buildings, including the abbey church, were destroyed in the years following the Revolution, while the rest were converted into a textile factory by the industrialist André Hartmann. This factory was also destroyed during World War I, leaving only the abbot's residence and some cloister ruins.
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.
