Since 1894, the wooded Poppenberg has had a 33.5 m high observation tower in steel framework construction built by the Nordhausen branch of the Harz Club, which was named after Prince Otto zu Stolberg-Wernigerode. On the occasion of the dedication of the tower on July 12, 1894, the mountain peak was christened Fürst-Otto-Höhe in honor of the forest owner. The tower was renovated in 1994.[2] When visibility is good, it offers a comprehensive view of the southern Harz, the Lower Harz with the Joseph Cross on the Großer Auerberg, the Goldene Aue and the Kyffhäuser.

The old turning body has fallen over in the meantime. You can still see the remains of the old spiral staircase that long ago allowed visitors to climb to the platform in the treetop.

I've been here so many times now, in every season. The first time was an absolute challenge for me with my fear of heights. But now it gets better with every climb. And the view is sensational anyway.
