The Neptune Fountain is a wall fountain from 1885 in Baden-Baden's pedestrian zone, located on the corner of Lange Straße and Mauergässchen.
Two curved fish carved in relief decorate the centre of the fountain, while the mouth of a downward-looking head in the middle serves as a source of water.
Note for the thirsty:
Fill up your water bottles here. The tap water gushing from the fountains is continuously analysed. The fountains themselves are also regularly cleaned and inspected.
