The MMM Ortles museum is located in Solda at an altitude of about 1,900 metres. It deals with the theme of ice through the exhibition of paintings with views of the Ortles and equipment, ancient and modern, which were used in ice climbing and ice climbing, skiing and expeditions to the poles, while outside the real ice of the peaks embrace the valley and the museum.
This building was built from scratch thanks to the collaboration of Reinhold Messner with architect Arnold Gapp. Access to this structure is through a large opening cut out on the side of a small hill: once inside, a ramp leads deep into the ground like an artificial cave, made of exposed reinforced concrete. The structure is illuminated by natural light coming from above thanks to a long cut on the surface of the ground, a cut that looks almost like a glacier crevasse.
