Where was Die Glocke built?

Transcript

In a secret facility deep in the mountains of Poland, Nazi scientists allegedly developed a mysterious device known as Dlock, the bell. It pulsed with strange energy. Some said it was a time machine. Others claimed it was anti-gravity technology. Witnesses described a glowing object that warped reality itself.

When the war ended, the bell vanished. Was it destroyed, hidden, or stolen by the Allies or Soviets? No blueprints have surfaced. Just a silent concrete ring in the forest and questions without answers.
