According to legend, three leaders from Uri, Schwyz, and Unterwalden met in Rütli, a secluded meadow overlooking Lake Lucerne and Sisikon, to swear an oath and create the Swiss Confederation.

For example, it is often found in Switzerland on the shores of Lakes Thun and Brienz, around Lake Uri, in the Glarus Alps, in the Rhine Valley and in the Lower Engadine, according to Bioterra.
