Katharinenkirche (St. Catherine's Church) was an important mediaeval church, destroyed during the Second World War and preserved as a ruin.
St. Catherine's was the church of a former Dominican convent, in the Diocese of Bamberg, famous for its Medieval Library. It was founded in 1295 by Konrad von Neumarkt and his wife Adelheid, patricians of the Pfinzig family. In the Middle Ages it had an important medieval library. After the Reformation, it became a Lutheran church. The convent was closed in 1596 after the last inhabitant died.
The church was associated with the Meistersingers who met there from 1620 to 1778, and is featured in the opening scene of Richard Wagner's opera Die Meistersinger von Nürnberg.
Although destroyed by air raids in 1945, it was partially restored (1970–71) and is used for events such as open-air concerts.
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.
