The Ley Arboretum
Our arboretum was designed and created by Karl Ley in 1998 as an ecological compensation area between company-owned land and the Swist meadow. More than 370 plants representing over 150 different varieties and species were planted in a strict geometric layout, in equilateral triangles. With this layout, people have the impression of being in the centre of the arboretum from whichever vantage point they are looking at it from. Karl Ley called this “democratic Baroque”.
