The Graduation Tower in Hamm's Kurpark is a unique open-air wellness facility located in the city of Hamm. The structure is an impressive wooden construction filled with bundles of blackthorn. This place is rightfully considered the "city's sea," as the air here is saturated with beneficial trace elements and moisture, creating a seaside effect in the heart of Germany.

The principle behind this giant inhalation unit is simple yet effective: natural brine slowly trickles down the blackthorn branches. As it evaporates, the air around the tower cools and becomes saturated with tiny salt particles — aerosols. Breathing this air is extremely beneficial for people with respiratory conditions and allergies, as well as for general immune system support.
The tower itself is impressive in size: it is about 42 meters long and reaches nearly 10 meters in height. For the convenience of visitors, a covered walkway has been built on the eastern side, allowing for "salt baths" even in rainy weather while enjoying the peace and tranquility of the Kurpark.
