The Herz-Jesu-Kirche is the largest church in Graz. It was designed down to the last detail by architect Georg Hauberrisser and constructed from 1881 to 1887.
The church was designed in the Neogothic style, with a large, high nave and under-church. The tower is 109.6 meters tall, making it the third-highest church tower in Austria. Of special note are the stained glass windows, which are among the few extant examples in Austria of Neogothic stained glass.
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.
