Blaubeuren Abbey was a house of the Benedictine Order founded in 1085 by the Counts of Rück and Tübingen, against the background of the Investiture Controversy and the Hirsau Reforms. The first abbot, Adzelinus, and monks were from Hirsau Abbey. Abbot Fabri was closely involved with the foundation of the University of Tübingen in 1477. In 1493 the high altar was created. The choir stalls by Jörg Syrlin the younger are of a similar date.
The Reformation saw the end of the Roman Catholic monastery, from which the monks were expelled in 1535, returning for a short time between 1549 and 1562. In 1563 the first Protestant abbot was appointed, and in 1565 a choir school was opened in the premises. During the Thirty Years' War the monks returned again in 1630 and yet again in 1648, but were expelled; the choir school closed in 1630 and reopened in 1650. It was finally shut down in 1807.
A few years later in 1817 Blaubeuren became a Protestant seminary with an attached boarding school, which has remained to the present, except for a closure during World War II. The school now operates in co-operation with the similar establishment at Maulbronn Abbey: see Evangelical Seminaries of Maulbronn and Blaubeuren.
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.
