The New Cathedral (Mariä-Empfängnis-Dom) construction plans were started in 1855 by Bishop Franz-Josef Rudigier. The first stone was laid in 1862. In 1924 Bishop Johannes Maria Gföllner consecrated the finished building as the Cathedral of the Immaculate Conception. The plans, drawn by the master builder of the Archdiocese of Cologne, Vincenz Statz, were made in the French high Gothic style.
With 20,000 seats, the cathedral is the largest (130 meters long, and the ground 5,170 square meters), but not the highest, church in Austria. The originally-planned, higher spire was not approved, because in Austria-Hungary at the time, no building was allowed to be taller than the South Tower of the St. Stephen's Cathedral in Vienna. At 135 m, the New Cathedral is two meters shorter than the Viennese cathedral.
Particularly noteworthy are the cathedral's stained-glass windows. The most famous is the Linz Window, which depicts the history of Linz. The windows also contain portraits of the various sponsors of the church's construction. During the Second World War some windows, particularly in the southern part of the cathedral, were damaged. Instead of restoring the original windows, they have been replaced with windows displaying modern art. Also noteworthy is the nativity scene in the church burial vault, with its figures made by S. Osterrieder, and the display of the regalia of Bishop Rudigier.
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.
