The Nibelungenwerk (also known as the Nibelungenwerke or Ni-Werk) was the largest and most modern tank assembly factory in Nazi Germany, located near the Austrian town of St. Valentin. As the only German tank production facility which had a well-structured production line, the Nibelungenwerk produced more than half of all of Nazi Germany's Panzer IV tanks.
