Cismar Abbey was a Benedictine monastery founded in 1238 by Count Adolf IV of Holstein as alternative accommodation for Benedictine monks from Lübeck. In the mid-15th century it was one of the six original members of the influential Bursfelde Congregation, a Benedictine reform movement. After three prosperous centuries, based largely on its possession of a relic of the blood of Christ and a healing spring dedicated to John the Baptist, which made it a centre of pilgrimage, it was dissolved in 1561 during the secularisation brought about by the Reformation. The monastic library is preserved in the Danish Royal Library in Copenhagen.
The abbey is famous for its carved altar, dating from early in the 14th century, still in place in the church. The other surviving buildings, after a wide variety of secular uses, now serve as a museum.
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.
