Svalbard is one of Europe’s last great wildernesses, an untamed Norwegian archipelago 650 miles from the North Pole, where polar bears outnumber people and stocky reindeer regularly trundle into town. The primary settlement, Longyearbyen, sits high above the Arctic Circle amid rocky crags and ice-clogged fjords. It spends several months of the year in the eerie darkness of the polar night, which is perpetual during this time save for the ethereal glow of the northern lights.
