Context

History in 5 minutes

Enough to make what you are looking at legible.

  1. 1100–1500

    Læsø develops a massive medieval salt-boiling industry supplying fish curers across Scandinavia, until all island forests are burned for firewood.

  2. 1600s

    With no timber or straw left on the deforested island, resourceful women begin thatching roofs with dried ocean eelgrass washed ashore, creating the unique Tanghuse.

  3. 1991

    Archaeologist Jens Vellev revives the historic salt-boiling works, establishing Læsø Salt as one of Denmark's most celebrated artisan brands.
