Graduation Tower in Radlin, Salt evaporation tower in Radlin, Poland

The Graduation Tower in Radlin is a structure with wooden frames filled with blackthorn branches, positioned over salt water that trickles downward. The water flows slowly and creates mineral-rich mist as it passes through the branches.

The tower opened in 2014 as part of modernization efforts in the Upper Silesian region. It revived historical salt extraction techniques and adapted them for contemporary wellness use.

The wooden pavilion, designed by Jerzy Stożek, was the first graduation tower in the industrial part of Upper Silesia. Its brine has been supplied from Zabłocie, Ciechocinek, Dębowiec and Ustroń. In 2017 a Kneipp hydrotherapy pool was added, and a small park with benches and a pond serves as a rest area.

The tower stands in the northern part of Radlin, near the border with Rybnik. The site is freely accessible and includes a small park with benches and a pond, plus a Kneipp hydrotherapy pool added in 2017. The wooden structure is 8.2 m high, 3.95 m wide and 24 m long.

The blackthorn branches that form the core of the structure must be completely replaced every five to ten years as they wear from constant water flow. This regular replacement is essential to maintain the effectiveness of the salt water evaporation process.
