The Regensburg Museum of History, currently resides in a former Minorite monastery, is a museum of the history, art and culture of Regensburg and eastern Bavaria from the Stone Age to the present day.
The former monastery of St Salvator, located in the city's Dachauplatz district, was founded in 1221 by the Bishop of Regensburg Konrad IV of Frontenhausen, Count Otto VIII of Bavaria, and King Henry VII. The three-naved basilica church was considered the largest church of the order in southern Germany until its closure in 1799.
The church and most of its monastic buildings survived, with the monastic buildings converted as barracks and billets for the Bavarian Army, and the church as a customs hall, a drill hall and a hotel until it became the location of the Regensburg Museum of History in 1931.
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.
