OBVERSE

The obverse depicts a bird's-eye view of Switzerland's largest lake. The landscapes surrounding the lake are delineated by contour lines towards the edge of the coin. The name of the lake appears in cursive lettering next to the image, harmoniously integrating into the landscapes of the cantons of Geneva, Vaud, and Valais, as well as France.

On the reverse, all special coins in the new "Swiss Lakes" series are adorned with a striking graphic symbolizing Switzerland's role as Europe's water tower. The coin's edge features the face value of 20 Swiss francs, the inscription "CONFOEDERATIO HELVETICA", the year of issue 2026, and the mint mark B for Swissmint.
