Its size is about 6,6 m x 3,9 m and it shows the Lake of Lucerne with Lucerne, Unterwalden, Zug and parts of the cantons Uri, Schwyz and Berne. The relief of Franz Ludwig Pfyffer is the oldest preserved large relief model of Switzerland.
At a scale of about 1:12’000 for the horizontal and 1:10’000 for the vertical direction it represents topographically an area of 4’100 km2 and as such about 1/10 of Switzerland. The model is constructed from pieces of timber, bricks, charcoal and cardboard with a mixture of gypsum, sand and beeswax as the top layer. Since 1873, this masterpiece is on display in the Gletschergarten Museum in Lucerne. The relief model of Franz Ludwig Pfyffer served as a basis for the several printed maps issued at the end of the 18th century.
