The Burgtheater (Imperial Court Theatre) opened on 14 March 1741, the creation of the Habsburg Empress Maria Theresa of Austria who wanted a theatre next to her palace. Three Mozart operas premiered there. The theatre's first building adjoined the Hofburg at Michaelerplatz, opposite St. Michael's Church. The theatre was moved to a new building at the Ringstraße in 1888 designed by Gottfried Semper and Karl Freiherr von Hasenauer.
On March 12, 1945 the Burgtheater was largely destroyed in a bombing raid, and, one month later, on April 12, 1945, it was further damaged by a fire of unknown origin. After the war, the theatre was restored between 1953 and 1955. The classic Burgtheater style and the Burgtheater-German language were trend-setting for German language theatres.
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.
