Tunnelbelüftungsgebäude am Königstuhl

The ventilation shaft building on Königstuhl is a stone structure featuring a tower design with a square base that rises prominently above the forest landscape near Johannes-Hoops-Way. Its construction reflects practical industrial engineering with clear geometric forms.

The building was constructed in 1912 to ventilate the railway tunnel running beneath Königstuhl, releasing gases from diesel and steam locomotives. This function ended in 1971 when electrification of the rail line made the ventilation system unnecessary.

The structure reflects early 20th-century industrial design, with architectural elements that echo medieval fortification styles, revealing how engineers approached practical challenges of that era.

The building was converted into residential space during the 1990s and sits in a wooded area best reached on foot. Sturdy shoes are recommended since the path involves walking up wooded slopes.

Next to the building grows a large sequoia tree planted during the original construction period, making it roughly the same age as the structure itself. This tree serves as a living reminder of the site's industrial past.
