The Monte Rosa Hut (2,883 m) is the only mountain hut in the massif owned by the Swiss Alpine Club. It is situated on the Plattje, a rocky island between the Gorner and Grenz glaciers. It is accessible from Rotenboden, a station on the Gornergratbahn line. The hut was inaugurated in 1894 and rebuilt in 1940. In 2009, a new high technology mountain hut was inaugurated. The five-story crystal-shaped building is designed to obtain 90 per cent of its power needs from the sun and will be used as a research station.
