The Tellskapelle is located on the Tellsplatte or Tellenplatte on the shore of Lake Lucerne at the foot of the Axenberg cliffs, in the Sisikon municipality, canton of Uri, Switzerland. It is across the Bay of Uri from the Rütli, some 4.3 km away.
The Catholic chapel marks the site where according to legend, William Tell during a storm leapt from the boat of his captors 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.
