Kochbrunnen

Kochbrunnen is a hot mineral spring in Wiesbaden that continuously brings warm water from deep underground to the surface. The water supplies bathing facilities and provides heating for buildings throughout the city.

The water was noted in medieval times and later known by different names before receiving its current one. Over time the spring was increasingly developed and used to supply city facilities and provide heating.

The spring's name refers to the hot temperature of the water, which has been used by locals and visitors for centuries. You can see the yellowish deposits that form when the warm water comes into contact with air at the surface.

The location is central in Wiesbaden and easily accessible, with the warm springs visible in their natural setting. Keep in mind that the water is very hot and caution is needed when approaching the source.

The water changes color and smell when exposed to air and left standing for a time. These changes show chemical processes happening in the spring that any visitor can observe.
