Nonnberg Abbey is a Benedictine monastery in Salzburg founded ca. 714 by Saint Rupert of Salzburg. It is the oldest women's religious house in the German-speaking world. Its first abbess was Saint Erentrudis of Salzburg, who was either a niece or a sister of Saint Rupert.
The abbey was independent of the founding house from 987 and was re-built in about 1000. This building was largely destroyed in a fire of 1423. Reconstruction took place between 1464 and 1509.
The nunnery′s church Maria Himmelfahrt is Salzburg′s oldest church dedicated to the holy Virgin Mary and is one of the most significant churches of the city. It was built in late-gothic style with three naves from 1464 to 1506. In 1624 the church was enlarged by the addition of three side chapels. A refurbishment in the Baroque style took place in the 1880s. The church contains a Romanesque crypt that visitors should note, with the tomb of St. Erentrudis. The entrances to the crypt are in the side-naves.
Through Maria Augusta Kutschera, later Maria Augusta von Trapp, who was a postulant in the abbey after World War I and whose life was the basis for the film The Sound of Music, the abbey has acquired international fame. The Mother Abbess during Maria's time at Nonnberg was Sister Virgilia Lütz (1869-1949).
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.
