The story of the eelgrass roofs at Læsø is one of necessity, craftsmanship and showing off. Women invented the roofing method when scarcity on the island drew all the men out sailing. The thick, bio-based roofs can last for 400 years and by that outperform almost any other roofing material. Hear the story from the closest one can come to the source: Henning Johansen, the current eelgrass thatcher from Læsø and Kirsten Lynge, co-founder of Søuld, who grew up at Læsø herself.
