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 Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
