Findlingsgarten Grenchen - Switzerland
Around 60 of the 300 or so boulders dug up when the motorway was constructed can now be seen in this specially designed boulder garden. As well as gneiss and granite, the garden also contains examples of limestones and sandstones. Boards explain how the rocks were created millions of years ago when the alpine folds began to form, and were then transported to Grenchen by the glaciers tens of thousands of years ago.
