Already in 1890 began the planning of the donated by Cornelius Wilhelm von Heyl well. First of all, Stadtbaumeister Hofmann was entrusted with this project. The plan was to set up a four-figured work of art in honor of the 'four main acts of the Nibelungen saga', crowned by a Siegfried figure. The location chosen was Hagenstraße / Marktplatz next to the Dreifaltigkeitskirche. The idea for the construction of the well was taken up much later - albeit considerably smaller - again. The Siegfried fountain came after war-related delays in 1921 to the lineup. In contrast to the Cornelianum the Siegfried fountain survived the air raids in the Second World War almost intact.
