OPENING ON 16-06-2017 The present-day Hotel Bella Lui – "beautiful light" in the ancient Valais dialect – was built in 1930 and stands today as a listed building, testimony to modernist architecture. It was originally opened as a luxury sanatorium. Later it served amongst others as a spa and holiday home. The hotel will close in September and the structural alterations to transform it into a youth hostel are expected to last eight months.
