Seaweed has been an important source of income at Limfjorden, and was back in the day collected, dried, cleaned and pressed to be used in mattresses, as fertilizer, as roofing, fodder and for making starch. The furniture factories Getama and Skalma started based on the usage of seaweed, and they still exist today, however, they do not use seaweed in their production anymore. The seaweed was pressed into large blocks, and stored in so called tanghuse (seaweed houses). It is possible to see one of these houses in Sundstrup, where you can also find additional information on the history and usage of seaweed in production.
The house now functions as primitive accommodation for cyclists, hikers, and other travellers.
