Standing in the salt hut, listening to the salt-maker's tales of Læsø Salt, you are sure to be entranced by the atmosphere. With the hut's beam constructions, the simmering of the water, and the rays of light mingling with the steam and the smoke from the fire, you are taken back in time.
It is the salt maker's responsibility to ensure that the salt water in the iron pans maintains the correct temperature. To control this, the salt maker uses a wooden rake which he pulls through the water. It is also the salt maker who shares all there is to know about his trade and the history of salt on Læsø. He tells these stories completely free of charge for all visitors who wish to listen, every HOUR from 10.00-16.00 from 1 May til 1 October, as well as during Easter and the autumn half-term holiday.
Today, as in the Middle Ages, the salt water is pulled from wells on Rønnerne. A combination of geology, winter storms and a dry climate means that the ground water gets a very high saline content. Several times during winter, the seawater floods the flatlands of Rønnerne, and then during the summer months, there iss a high rate of evaporation from the sandy surface. At a depth of approximately 2 metres down through the sand, the water meets a solid layer of blue clay, which prevents it from seeping further. As such, the water remains relatively near the surface and evaporates. The remaining water can reach a saline level of up to 15 percent. In comparison, the saline concentration in Kattegat is around 2-3 percent.
From 1990 and every year for the following 15 years, archaeologists, led by Jens Vellev and architect Hans Langballe, have carried out archaeological excavations on Læsø. The oldest salt hut at Læsø Saltsyderi is a reconstruction of a hut from the 12th century. It was opened on Constitution Day (5th June) in 1991. In 1998, Læsø Saltsyderi built a new large, double hut, which is a reconstruction of a building which was excavated on Langerøn.

Salt and psoriasis
It's a well-known fact that saltwater treatment helps to alleviate and soothe the skin condition called psoriasis. It is also known that salt, iodine and magnesium have a greater effect in combination. After 1 week of evaporation, the salt water that remains in the pans is a highly saturated brine with a high content of iodine and magnesium.
Salt spa in the church
Læsø Kur is a spa resort based on the salty groundwater from Rønnerne. In addition to the treatment of psoriasis patients, the resort offers spa and wellness treatments to all its guests.
School camps
School classes can book a variety of special activities at Læsø Salt.
