The Apollinaris Fountain
The Apollinaris Fountain in the Heppingen district was discovered by Georg Kreuzberg in the middle of the 19th century. During this time, he acquired a vineyard in the neighbourhood of Bad Neuenahr. However, contrary to his expectations, the wine on this hill did not grow as he had hoped. In order to find out the reason for the poor growth of his vines, Kreuzberg carried out test drillings in 1852. To his surprise, he discovered carbonated water at a depth of 15 metres. The high concentration of CO2 in the soil proved to be the reason why the vines failed to thrive.
