Wasserschlössle

Wasserschlössle is a water storage structure with a castle-like facade built from sandstone and concrete stone blocks in Freiburg's Sternwald forest. The building conceals an underground facility that stores and distributes drinking water to the surrounding area.

Built between 1895 and 1896 by the Brenzinger & Cie company, the structure served as the main water supply for eastern Freiburg throughout the 1900s. Its construction reflects the period when German cities were developing modern water infrastructure.

The design draws from Freiburg's town seal dating back to 1245, which appears on manhole covers scattered across the old town and adorns the mayor's official chain. This approach links engineering with local heritage, making the city's historical identity part of everyday infrastructure.

The structure sits within Sternwald forest and is accessible from hiking trails, though entry inside is typically not permitted. It is worth viewing the architectural facade up close to appreciate the contrast between its castle-like appearance and its purely technical function.

Despite its grand castle appearance, the structure operates entirely on gravity without any mechanical pumps. This simple principle allows water to reach all connected households without consuming electricity.
