The hotel, built in 1870, profited from the pass traffic at Segantini's time. Travelers took the stagecoach from Chur to the Engadine every day. The Hotel Piz Mitgel owns a land register right to an unobstructed view of the Piz d'Err that is still valid today. That is why the Peterelli house was built somewhat set back.
The "Kurhaus Piz Michel" is built in 1870 by the Wasescha brothers. In addition to passport traffic, they set their sights on spa tourism. In the summer of 1874, the hotel advertised itself in a newspaper advertisement with the headline "Climatischer Curort Schweiningen" as an ideal place for a longer stay for families and climatic spa guests as well as for tourists. The number of tourists transported over the Julier increased steadily. In 1888 there were 14'471; in 1900 already 22'706.
With the opening of the Albulaline of the Rhaetian Railway, the travel time from Chur to the Upper Engadine was reduced from 12 to 4 hours as of 1903. The traffic through the Oberhalbstein collapses, in 1908 only 1527 postal passengers are transported.
After various changes of ownership, the hotel passed into the possession of the Waldegg family in 1961 and subsequently to Sepp and Regina Waldegg-Noseda.
In April 2021, the Piz Mitgel Val Surses Foundation buys the hotel complex, renovates it until the beginning of December 2021. In December, in a glamorous reopening, the glory days of the 1920s should return.
