The first small Starhemberg castle was built by Ottokar III, Margrave of Styria between 1140 and 1145. At the time, the Piesting river was the border between Styria and the March of Austria. In 1192, Styria—and, thus, the castle—was acquired by the Babenbergs. The last Babenberger duke of Austria, Frederick II the Warlike, expanded and fortified the castle, leaving Starhemberg as one of the most important castles in Lower Austria in the 13th century. In wartime, the archives and the family treasure was hidden here, and were guarded by the Teutonic Knights.
After the Battle on the Marchfeld in 1278, the castle was acquired by the Habsburgs. In 1482, the castle was captured by Matthias Corvinus, king of Hungary. In 1683, the castle offered protection from the Turks to the surrounding population.
To escape a new roof-tax the counts of Heusenstamm around 1800 had the roof covering removed, as well as doors and window frames, beginning the decline of the castle. Around 1870, a large part of the great hall collapsed. Until the mid-20th century, the ruins were used for the extraction of construction materials by the local population.
In the spring of 1945 a unit of the Waffen-SS used the ruined tower above the chapel as an observation post. Russian artillery fire inflicted heavy damage to the walls.
In the second half of the 20th century a local organisation, Friends of the Castle Starhemberg, has sought to restore the ruins. Since 2007, the castle has been closed to visitors, for security.
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.
