gradierwerk “Louise” Bad Sulza

The beneficial effects of salt north-east of Apolda in the Weimarer Land.

The history of salt boiling in Bad Sulza dates back to 1064. As early as the early modern period, the health-promoting effects associated with salt extraction were noticed. Three imposing graduation towers once dominated the townscape of Bad Sulza, the largest of which was more than 224 m long and 15 m high. The “Louise” graduation house has been preserved and bears witness to remarkable construction and craftsmanship, as many of its parts are still in their original condition today.

Louise graduation house with walkway and atomiser hall

The “Louise” graduation house is 142 m long today. Every day it “consumes” 6-8 m³ of brine, on the one hand on the 890 m² thorn wall and on the other hand in the 200 m² atomiser hall, where guests are finely sprayed with the naturally iodine- and iron-rich water.

Only blackthorn branches are used for the thorn wall. This type of sloe is particularly robust, so the brine does not decompose the branches.Even if the fibrous wood gives the impression in some places, the structure is by no means in danger of collapsing. Over the centuries, all the beams have been impregnated with brine. This particular type of preservation makes the wood very stable and will certainly defy the seasons for a very long time.

The health-promoting effect of brine

Brine is said to have health-promoting effects on respiratory diseases, cardiovascular diseases, musculoskeletal diseases, skin diseases, psychosomatic diseases and metabolic diseases. Those who would like to enjoy the brine in Bad Sulza in combination with wellness, warmth and music should visit the Toskana Therme in the immediate vicinity of the graduation house.
