Revered climber Reinhold Messner has spent the last 12 years creating his Messner Mountain Museum – six very different museums spread across South Tyrol, in northern Italy, each location focusing on a different aspect of mountains and mountaineering. The jewel in the crown is the Zaha Hadid-designed MMM Corones, which opened in 2015. Sitting on top of/inside the Kronplatz mountain at 2,275m, the building is shaped like a bird’s foot. The top level hosts the entry area and from there stairways lead like waterfalls down to the exhibition levels. On the lowest floor visitors can look out of huge viewing windows or step out into a viewing platform with a 240-degree panorama from the Zillertal Alps to the Dolomites. Hadid said, “The idea is that visitors can descend within the mountain to explore its caverns and grottos, before emerging through the mountain wall on the other side… to spectacular, panoramic views.” The bulk of the museum is created from prefabricated concrete panels, light on the outside and darker on the inside, to match the colour of anthracite found below the surface. The walls are between 40-50cm thick, while its roof, supporting the replaced earth and rock that embeds the museum into the mountain, is up to 70cm thick.
