For four years, from 1979 to 1983 the international boarding school and the hotel and tourism school ran in tandem.
Then in 1983, the doors closed to secondary school children, and the school’s sole focus became hotels and tourism. There were approximately 170 students.
On a Sunday evening in April 1985, a huge fire destroyed the main building. All 180 students and resident staff members were safely evacuated, and de-camped to the Hotel Mirabeau in Montana for two years whilst the campus was being rebuilt.
Despite considerable destruction to the property and its contents, the School only lost one day of classes as arrangements were immediately made to house students and teaching facilities in three hotels in Montana. Construction of new buildings began in May 1986.
In 1987, the school re-opened its doors. The new building was designed to accommodate more students and with greater purposed-built facilities for vocational training. The school made an agreement with the Swiss Hoteliers Association (which lasted till 2005) enabling them to officially offer the SHA diploma, and Les Roches was put firmly on the hospitality education map.
