The structure uses approximately 25,000 bundles of blackthorn (Prunus spinosa) to facilitate the evaporation of the brine.
The graduation tower is part of the largest coherent graduation complex in the Palatinate region.
Historically, the site was used to increase the salt concentration of the spring water to make salt extraction more energy-efficient.
The inhalation effect is caused by the salt-heavy mist generated as brine trickles through the brushwood walls.
The wood used for the framework is primarily oak, chosen for its resistance to the constant salt exposure.
The Gradierbau in Bad Dürkheim is one of the largest remaining graduation towers in Germany, stretching over 333 meters in length. It functions as an open-air inhalation facility where brine trickles over stacked blackthorn bundles to saturate the air with salt aerosol. This process creates a sea-air-like microclimate intended to aid respiratory health. The structure serves as the centerpiece of the local spa park and is integrated into a larger wellness complex. Visitors walk along the wooden scaffolding to inhale the mineral-rich air directly from the source. The tower was originally constructed in the 18th century for salt production before transitioning to a health facility. It remains a focal point of Bad Dürkheim's identity as a spa town. The site is maintained by the local municipality and remains fully operational for visitors.
From the elevated wooden walkways for a perspective across the length of the massive wooden structure.
Visit on a breezy day to maximize the distribution of the salt mist in the air.
Combine your walk with a visit to the neighboring Kurpark for a full therapeutic experience.
Wear light layers, as the humidity and temperature near the brine walls can differ significantly from the surrounding area.
Avoid touching the brine-soaked blackthorn walls, as they are sharp and covered in mineral deposits.
The outdoor pathways may be inaccessible during extreme winter weather or periods of high wind.
