The Glaciorium

An interpretation centre to answer all the questions that visitors ask themselves when they are faced with a glacier such as the Mer de Glace. The Glaciorium also responds to questions related to climate and the environment. A glacier is an indicator of the climate, a witness to climate change. It is also the memory of the planet and life on Earth. The space also addresses the culture of men that was built around glaciers. And tomorrow? What future for glaciers?

To accompany the life of the glacier, the glaciorum will evolve, find the main stages of the project by consulting the website: https://www.montblancnaturalresort.com/fr/projet-montenvers
