Rütli

Rütli or Grütli is a mountain meadow on Lake Lucerne, in the Seelisberg municipality of the Swiss canton of Uri.
It is the site of the Rütlischwur in traditional Swiss historiography, the oath marking the foundation of the original Swiss Confederacy.
As such it is treated as a national monument of Switzerland. Since 1860, the Schweizerische Gemeinnützige Gesellschaft has organized a celebration at the site
on Swiss National Day , since 1994 recognized as a public holiday.

The Rütli became a site of symbolic importance for Swiss national identity in the early 18th century, with incipient National Romanticism.
In the 1780s, there were proposals to erect a monument to Liberty at the site.
Under the Helvetic Republic, the Rütli became a site of pilgrimage for conservative dissidents. In 1804, the year after the dissolution of the Helvetic Republic, Friedrich Schiller published his Willam Tell, which dramatized the Rütli oath. A patriotic Rütlilied was written by Johann Krauer and Franz Joseph Greith in 1820.
