The glacial erratics exhibition

"Of the total number of over 300 blocks found during the construction of the motorway, around 60 typical stones have been put on show in Grenchen. Limestone and sandstone, etc. are on display alongside primary rocks such as gneiss and granite. Ten well-illustrated and informative panels explain how these blocks were formed by Alpine folds millions of year ago and then transported by the glaciers to Grenchen tens of thousands of years ago. The information panels explain the origins of the ice ages as well as the fauna at that time."
