This recently built chalet lies on the outskirts of Crans-Montana and probably couldn't be built if it was in the town limits. Why? Thank Russian oligarchs. Years ago Russian oligarchs pretty much invaded Switzerland buying up big bucks properties in the high-end ski resorts like St. Moritz, Gstaad and Crans-Montana. Alarmed by this invasion, laws were enacted severely restricting where and what foreigners could purchase. Many properties would be used for a month (usually over Christmas) and sit empty the rest of the year. Laws were passed saying the properties had to be available for rent when not in use.
