The fastest growing religion in Iceland is Norse paganism.

Floating in a hot spring, snow falling from the night sky, John Laurenson meets Teresa Drofn. A 25 year-old Heathen, Teresa describes her return to the religion of her Viking forebears as a renewal of a unique spiritual relationship with nature.

A millennium after it was banned in exchange for Christianity, John explores why Icelanders are returning to the faith. At a ‘blot’, or sacred ceremony John hears a priestess read aloud from the Eddas, an ancient Icelandic text serving as scripture for the new heathens of Europe. In the old days at a ‘blot’, there’d be animal, even human sacrifices. Today they share in traditional Viking food, horse and whale, sheep’s head, puffin pâté and rotten shark.

Visiting the site of a newly planned Heathen temple John meets high priest Hilmar Örn Hilmarsson. Hilmar has presided over hundreds of weddings and seen his own congregation increase six-fold within a single decade. This new Heathen house of worship, the first in a thousand years, will be aligned with the sun’s path and burrowed deep into a hill near the city’s airport.
