Obere Burg ('Upper Castle'), also known colloquially as Burg Neu-Schellenberg, is the larger and older one of the two ruined castles in Schellenberg. Its construction was finished already around 1200. The castles's first appearance in written records occurred on the 10th of January 1348. According to current estimates, it was inhabited until roughly the 16th century, when it was abandoned and ceased to function as a residence. In the following centuries, the castle lost its military purpose and became a ruin. In 1956, Franz Joseph II, Prince of Liechtenstein handed over ownership of the heavily overgrown ruin to the Historical Association of the Principality of Liechtenstein. This institution is the current owner and caretaker of the ruin and oversees its research, upkeep and preservation.
The castle ruin located in the municipality of Schellenberg, Liechtenstein. It lies at the western edge of Hinterschloss, one of the burroughs in the village of Neu-Schellenberg. It is freely open to tourists. Due to its close proximity to Hinterschloss, it is probably the most easily accessible of all Liechtenstein castles. Obere Burg is one of the five existing castles in Liechtenstein and one of the three ruined ones in the country.
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.
