The Tellskapelle ('Tell's chapel') on the shore of Lake Lucerne. The Catholic chapel marks the site where according to legend, William Tell during a storm leapt from the boat of his captors (the Tellensprung 'leap of Tell') and escaped, allowing him to assassinate the tyrant Gessler and initiate the rebellion that led to the foundation of the Old Swiss Confederacy. The Tellenplatte is first mentioned in 1470 in the White Book of Sarnen, as Tellen blatten.
The current chapel was built in 1879. It is decorated with four frescos by Ernst Stückelberg, realized in 1880-1882.
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.
