Originally, graduation towers were industrial buildings used to increase the salt concentration of the brine. Because, the higher the concentration, the sooner salt crystals are formed during boiling, and the sooner these salt crystals are formed, the less fuel is needed. For this reason, there were once three graduation works in the town, so that it was possible to grade even more efficiently - in other words, to increase the salt content. Today there is still our "Louise" - the only remaining graduation house in the village. It has two special features: first, a roof. So goodbye rainy weather. On the other hand, the inhalation and atomization hall is connected here. Here a very fine brine mist is produced by means of compressed air. Due to their size, these can penetrate deeper into the lungs. Hay fever sufferers, people with asthma or a cold swear by it. And everyone else simply enjoys an experience like "London in the thickest fog". The fine droplets of brine make it hard to see your hand in front of your eyes.
