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 city walls of Avila were built in the 11th century to protect the citizens from the Moors. They have been well maintained throughout the centuries and are now a major tourist attraction as well as a UNESCO World Heritage Site. Visitors can walk around about half of the length of the walls.
The layout of the city is an even quadrilateral with a perimeter of 2,516 m. Its walls, which consist in part of stones already used in earlier constructions, have an average thickness of 3 m. Access to the city is afforded by nine gates of different periods; twin 20 m high towers, linked by a semi-circular arch, flank the oldest ones, Puerta de San Vicente and Puerta del Alcázar.
