Like a day by the sea!The graduation buildings are the reason behind the smell of a fresh sea breeze in Bad Nauheim. They originally belonged to Bad Nauheim's saline, one of Europe's most modern salt refineries in the mid 18th century. The large constructions of blackthorn provide an ideal system which increases the concentration of mineral salts through water evaporation. Five of the former 23 graduation buildings are still preserved with a total length of 650 metres. The salty air also has a positive effect on the organism and moistens the air passages. The “Inhalatorium” (inhalation room), part of graduation building I, is open to visitors daily from April to October. Five units, each holding six tanks with mineral solutions, nebulize the 40 square metre large room producing a fine mist with a concentration of 2,7 percent salt. This condensed air notably helps in relieving respiratory diseases. Salt crystals enter the air passages clearing it of bacteria and decreasing the swelling of the mucous membranes. Inhalation ist particularly recommended after sports activities.Salt-seething at graduation building IEvery Wednesday, Saturday and Sunday from April to October, visitors watch the traditional “saltboiling” in the “Keltenpavillon” (Celtic pavilion) at the graduation building I between 3 and 6 pm. You even have the opportunity to produce your own salt under professional guidance.The archaelological “Kelten-Pavillon” provides information about the history of salt production in Bad Nauheim and about the life and work of the Celts (texts only in German).
