【Branch Excursion】The stroll in Lausanne-Garden

Saturday September 15, big sun and small chilly wind, there are 15 of us on the forecourt of Saint-François church in Lausanne.

Our guided walk begins inside the church in front of a pile of rubble: * Future Stone Age Project *! Surprised and whispered, did we choose the wrong guide or visit?

But no, we have before us the process of biomineralization or how the sand becomes stone and vice versa!

We are amazed!

The visit continues under the sun in a succession of parks and walks that few of us know.

The great pimprenelle, the guardians of the earth (a hundred small animals in raw earth), the murmur of the Vuachère in a giant cone and finally, the sundial of the mole with its 3D galleries.

But where is the open ground in our cities? This is the question we must ask ourselves!

A beautiful afternoon full of explanations and discoveries!
