The Temple of Nature

In 1779, Lord Blair, an English gentleman, finds himself caught in a storm in the Montenvers. The shelter under the stone was so uncomfortable that he had a hut built of planks and dry stones, with an inscription above the door: “Blair’s Hospital – Utile Dulci”. Goethe spent a night there in November 1779!
Blair’s dilapidated cabin was soon too small. Marc Théodore Bourrit was in charge of organizing the construction of a more resistant building, to serve as a hospice and observatory for amateurs and scholars.

With a unique octagonal piece, the Temple of Nature is considered to be the oldest refuge in the Alps.Today, as a museum, the Temple of Nature is a place steeped in history that is not to be missed during your excursion.
