You pass a curious building made of Vosges sandstone. This is the Haut-Koenigsbourg pumping station and its neighbouring building, which houses the spring catchment. Despite its modest dimensions, this building impresses with its neo-Romanesque style. It is reminiscent of the Metz railway station, also built in a style close to the 12th century, that of the time of the Hohenstaufen, the emperors of the Holy Roman Empire. On the top of the facade, there is a representation of the imperial eagle and the year 1901.
