Tellenburg Castle was built around 1200 by the Lords of Kien. After the Lords of Kien, the Lords of Wädenswil became the owners of the castle. They were followed by the Lords of Turn in 1312 and then later by the city of Bern. The original castle was expanded and repaired in the 13th or 14th centuries.
Under Bernese rule, the castle served as the administrative seat of the surrounding area until the creation of the Helvetic Republic in 1798. After 1798 it was used as a poor house. In 1885, the castle was gutted in a fire. It was never rebuilt and has slowly fallen into ruin.
Tellenburg Castle was built as an administrative center and toll station. Telle at beginning of the name likely comes from the German word for toll, Zoll, while burg simply means fortress.
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.
