The Monument to the Nibelungs or Nibelung Fountain is dedicated to a scene from the great medieval German epos: the meeting of Kriemhild, Queen of Burgundy, and Etzel, King of the Huns, in Tulln. It is depicted in a set of bronze sculptures by sculpture Michail Nogin.
The Nibelung Fountain is truly a sight to behold on summer nights. An integrated and esthetic light-water-stone composition of the fountain sculptor Hans Muhr lends the artwork even more depth: the fountains of water rise out of an open book – Lay of the Nibelung.
The fountains alternately become stronger on each side until their streams of water finally touch and mix – this feature also corresponds to the symbolism of two worlds, East and West, approaching each other in Tulln.
